Reminiscences from Colleagues
From Collin Bennett,
one of Tom’s co-authors:
I can't tell you how sorry I am to hear about Dr. Branson.
He was a great person and seemed to genuinely care about everyone. He
repeatedly went out of his way for me, but he seemed to do that with a
lot of people. I always thought of him as a friend, but he treated
everyone the same way, so maybe he wasn't my friend, but rather
everyone's.
I don't think an epitaph changes how someone is remembered, so I don't
really think that there is much to say about someone in a situation like
this. But if I knew that some words were going to be the last ones he
heard from me, I would have wanted them to be "Thank you."
Collin Bennett
March 24:
Sadness they tell me is
temporary, Tom was, is, my brother. I'm the 4th of the seven children.
Tom was, is, 3 years and 4 months older than I am, yet he never teased,
or picked on any of us, Tom was the one everyone got along with. He
taught me to play chess when I was 4 but he never let me win. He would
say, "you sure you want to move there", checkmate soon followed.
We did not know the level of Tom's many achievements, when we talked it
was about his wife and the girls, never about himself. Over the last
couple of years all seven of us had been together only twice, my niece's
wedding in 2004 and my sons last August. Words cannot express the
remorse of not getting together more often. We were busy that weekend,
he was busy the next, and on and on it went. When we were together we
had a great time but those times were too seldom. Well we had a reason
to get together this last week, don't wait for a "good" reason to get
together. Hug your wife or husband, brother or sister or a friend and
tell them how you feel. It's only been 12 days, it seems like 12 years
and I still am as sad as I was when I received the news. We love you and
miss you!

Tuesday, March 14
Friends,
The full obituary is in the Gazette today; the Press Citizen printed most of it but left out the details of the visitation etc., so they will reprint it in full tomorrow. The obituary has also been posted in Tom's home town, La Cross, WI.
Tom's family is present in full and doing all they can to help us through.
Some of my family will arrive next week and stay with us for a while.
Tom would be so proud of all of you. Sara, Eva and I feel strongly his spirit is present around us, trying as always to help us through.
Bless you all and please, live life to its fullest.
-Susanne.
Dear Department,
It was a truly sad message (received via Hans Plesner Jakobsen, our head of
department) which was in the mail this morning. Toms family, the department at
Iowa and Toms many friends around the world have suffered a great loss. Toms
character was much appreciated when he was in Denmark and I am just one among
the staff members in Copenhagen who made friends with him - in my case without
any great overlap in mathematical interests. I had looked forward to seeing him
again and playing tennis with him later this year on his planned visit to
Denmark, but now ...
Please convey my greatest sympathy and thanks to his family as well.
Yours sincerely,
-Flemming Topsoe
Tom Branson obtained his PhD from MIT in 1979 and worked at the
University of Iowa since 1985. He had an outstanding career in mathematical
research. His motivation came from geometry, physics, and symmetry and his work
is distinguished as a highly original blend of these three elements.
In the early 1980s his work on conformal invariance was significantly ahead of
its time. In all his research, he utilized to great effect the natural interplay
between this invariance and the underlying symmetry groups. It is a highly
influential theme and Tom Branson's work now motivates a thriving international
research effort in this direction.
In the early 1990s he introduced an extremely subtle quantity known as
"Branson's Q- curvature," which is now seen as absolutely fundamental in
conformal geometry. His recent work further developed Q-curvature and pursued
many other aspects of symmetry, invariance, and geometry too varied to list
here. Its impact will always be felt.
In addition to his substantial and continuing research effort, Tom Branson was
tireless and selfless in looking after students and in organizing workshops and
conferences. These efforts were always well beyond the call of duty. His
untimely death is deeply saddening and the mathematical community will miss him
sorely.

Tom Branson and I first met in 1992, when I took the graduate
course in analysis at Iowa. I later took differential geometry and general
relativity from Tom, and we went to the geometry seminar together.
When it came time for me to begin work with a thesis adviser, Tom and I agreed
to work together. We used to meet in his office for an hour every week. I worked
on a problem in conformal geometry, and in 1998, I received my Ph.D., with Tom
as my adviser.
Throughout the course of my work with Tom, I always felt that my specialty was
differential geometry. And yet over the years I have gained a deeper
appreciation of the fact that modern geometry often involves concepts and tools
from many different branches of mathematics. Tom had a strong knowledge
differential geometry and these other branches. This enabled him to write a very
large number of research papers. Tom wrote many of these papers on his own, but
he also worked with a very large number of collaborators, both in the U.S. and
abroad.
Tom gave me a very good thesis problem to work on. This was important, given the
complexity of the topics that Tom was interested in. My topic was simple enough
for a beginner and complex enough to provide a challenge. It also provided me
with an introduction to a very important area of current mathematical research.
After graduation, I moved to my current job here at the University of North
Dakota, but Tom and I stayed in touch via e-mail. He gave me some tips on how to
get my first article accepted for publication. Tom also helped me in other ways;
he was an organizer for several mathematical meetings, conferences, and special
programs, some of which I attended. Through these meetings I was able to
establish collaborations with other mathematicians.
One of the meetings I attended was the Midwest Geometry Conference at the
University of Iowa in November of 2000. At that time, the NSF grant for the
Midwest Geometry Conference was about to expire. So during the 2000 conference,
Tom held an organizational meeting to plan future conferences. He suggested that
the University of North Dakota hold one of the conferences in the series, and to
my amazement, everyone seemed agreeable to the idea. With the help of many
others, I prepared a new NSF grant proposal for the conference series. The NSF
eventually funded the proposal, and we held a successful conference here in
North Dakota!
For the last year or two I have been in less contact with Tom. I was working
with one or two other collaborators of my own. I also knew that Tom had other
responsibilities. But we still kept in touch.
Just this past Christmas, I extended my usual season's greetings. Tom sent me a
digital photo of his two daughters, one with bare feet, even though snow could
be seen in the background! At my request, he also sent me some advice on future
directions for my own research activities. Just the day before his passing, Tom
and I exchanged some messages concerning some preparations for yet another
special program that Tom was organizing!
I think Tom had a sincere love of mathematics. Upon questioning, he once told me
that he made "steady progress" in his research. He said he appreciated the fact
that other people were interested in the things he was doing for his research.
Another indication of Tom's love of mathematics is a short little conversation I
remember having had with him many years ago. The discussion turned to the idea
of administrative jobs and the possibility of getting promoted to a job as the
dean of the college or some higher position. His reply to this was that if he
had wanted to be a manager or an administrator, he would have simply taken a job
in industry. Now of course we all know that our society needs administrators and
managers, and I think Tom knew that too. But his career ambition was mathematics
itself. He was more interested in mathematics than in rising up the
administrative ranks!
I think Tom also had a sincere interest in the success of his students. He
wanted me to succeed, and he wanted his other students to succeed as well, both
at the undergraduate and graduate levels. We will certainly miss Tom. I extend
my sympathy to Susanne, Tom and Susanne's children, and to Tom's family and
friends!

Dear Sir
I just want to tell you how sorry I am that Tom Branson has left us. He was a
good friend of mine, I live in Luxembourg and have met him many times in France
before when he came to work at the university.
I would like to ask you to transmit my deep condoleances to his wife and his
children.
I'll keep him in my heart, he was a wonderful, straight, honest and kind man!
My heart is so heavy when I think of you Tom although I know
that you are light, a light as you have been to us down here and light in your
soul, flying away from us, flying over there, somewhere and you are happy.

From Ivan Avramidi:
I was shocked to hear the sad news about Tom. I will try to call Suzanne, but in
case I do not reach her, please express my deepest condolences to her. Tom will
always be missed by me as one of the nicest persons I have ever met. He has done
so much for me ...

From Vincent G.J. Rodgers:
Hi Palle, thank you for the message. It is crushing news.
Sadly,

From Rod Gover:
Dear Palle
I have just got news of this tragedy. Please pass on my wishes to Susanne and
the girls. This is really awful news.

From Bent Ørsted:
Thomas P. Branson was a well-known mathematician with over 70 published
scientific papers. His research interests spanned a large area of modern
mathematical physics and differential geometry, and he made several important
contributions to these subjects.
Thomas P. Branson found new classes of wave equations analogous to those for
zero-mass particles and made profound studies of their geometric properties; he
introduced a new curvature invariant now important in quantum field theory, and
he was a leading expert in calculating explicitly many other invariants
associated with differential equations arising in physics and geometry.

Kaere Palle
Jeg har netop talt med Bent i telefonen, og han naevnte at du ville tage dig af
nogle blomster til Tom, fra alle os der ikke har mulighed for at deltage. Tak
for det.
Tom var postdoc her ved instituttet i midten af 80'erne i en ret lang periode,
hvor ogsaa jeg selv var i samme situation.
Alle her er naturligvis rystet over at han er gaaet bort saa tidligt, og det
skaerer i hjertet at taenke paa Susanne og bornene. Tom var ogsaa ansat ved RUC
i en periode omkring 1990, samtidig med Gestur, og for mig var det nogle meget
frugtbare ugentlige moder vi havde. Vi skrev ogsaa et par faelles artikler paa
baggrund af disse moeder.
Venlig hilsen
Henrik.
Translation of Henrik Schlichtkrull's letter. [PJ: Apologies! The texture changes a little in translation.]
Dear Palle;
I just got off the phone with Bent [and learned the sad news that Tom died.] Bent said that you agreed to put together a flower arrangement for Tom, coming from all of us [over here] who will not be able to be there at the service.* Thanks!
Tom was a postdoc here at the Math Institute [University of Copenhagen] in the eighties for a fairly long period; where at that time I also held a similar research job.
Everyone here is deeply moved to learn of Tom's premature passing; and it breaks our heart thinking of the grief Susanne and the girls [must now experience.]
During a [shorter] period in the nineties, Tom was again in Copenhagen, visiting this time at RUC [a neighboring university]. This overlapped a period when Gestur [Olafsson] was there too. And this time for me, with weekly meetings [workshop seminars] stands out as especially fruitful and rewarding. In fact, we co-authored a couple of joint papers on the basis of these meetings.
Fond regards,
Henrik.
* Danish tradition: Names on a ribbon on the flower arrangement!
I was completely shocked by the news of Tom passing away. I wish
to express my deepest condolences to his wife Susanne and his daughters.
I knew Tom since 1996, when I came to the United States to become his PhD
student. He was a great teacher, a true mentor figure for me. The breadth of his
Mathematical insight shaped my own interests in Mathematics and inspired my own
research. I will always remember his great personality and his unique sense of
humor.
Tom's untimely death is a great loss for his family, the Department and for the
Math community.
Oleg Svidersky
Tom was a good friend of long standing. Perhaps our most famous
joint paper was the computation of that a_6 term in the heat trace expansion
for manifolds with boundary. We collaborated on a number of other papers --
visited me once at the UO and I visited him once at Iowa. I enjoyed our
collaboration both on scientific and on personal grounds. He will be missed.
Peter B Gilkey
Although I'd been keenly aware of Tom's deep and important work
on conformally invariant differential operators since the 1980s, I'd never had
the opportunity to meet him until 1999, when we both participated in a
conference he'd helped organize in Luminy, France. At that time, we immediately
hit it off, not only because of our many shared mathematical interests, but also
because of certain attitudes
toward life we shared as middle-aged fathers of young children. It was thus a
profound pleasure to re-encounter Tom at meetings in California, Canada, and
Taiwan over the course of the next few years. The conversations we shared there
have left an indelible impression on me. I will always remember Tom, not only
for his profound mathematical insights, but also for his great personal charm,
humor, and wit.
No words from a stranger could possibly help assuage the infinite feelings of
grief and loss his family must be experiencing at the present. But in the months
and years to come, as his daughters begin to take stock of who they are and
where they've come from, it may be a source of some consolation to realize that,
although their Dad's consuming passion for mathematics often took him far from
home, his love for his little girls always remained a core feature of his being
--- one that was apparent even to colleagues who knew him primarily as a
mathematician.
Claude LeBrun
From Alice Chang, and Paul Yang [Chang, Sun-Yung A.; Yang, Paul C.]; Professors of Mathematics; Princeton University.
In memory of Thomas Branson
We were shocked and deeply saddened by the news. It is difficult to accept such
a tragedy.
Our acquantance with Tom began with our interest in his work about conformally
covariant operators in 1990 nowadays often called Branson-Paneitz operators. We
had some joint work together on the
functional determinant of the conformal Laplacian on 4-manifold. We had learned
many things from Tom since then. It was a fruitful collaboration and one of the
key development in our career.
Over the years we gradually came to know Tom a bit beyond that as an outstanding
mathematician. He is a very kind, fair and responsible gentleman, who is about
the most hard working and dedicated
mathematician we ever met. We knew we can count on Tom to answer any questions
put to him, to show up on time at any meeting or workshop that he organized or
promised to attend. We were so glad for him when he married and began to
have a family.
The loss of Tom will be difficult for many of us to endure.
Alice and Paul
I met Tom when I was still a graduate student, fumbling for a
thesis problem; and I remember the first conversation we had about mathematics,
in the lobby of some hotel in Albequerque, New Mexico, in the late 80s. Tom was
friendly and very helpful; and it is not an exaggeration to say that I spent the
better part of my early career mining the rich veins of ideas in several of his
papers.
Over the years, Tom and I talked about mathematics many times and in many
places, but we also talked about our families, and other things that are
ultimately more important than math. He visited me at Notre Dame about a year
ago, and we enjoyed a wonderful dinner at my house with my wife and children.
Tom taught the kids some guessing games that he played with his girls. I
remember the kind way he smiled as my son repeatedly blurted out the wrong
answer, and how he entertained my oldest daughter with stories about his horses.
To Susanne and the girls, I offer my deepest sympathies. I will miss Tom as a
colleague and friend.
Sincerley,
Matt Gursky
Not having Tom as part of our community will be a great loss.
He was a wonderful colleague, always full of energy and ideas for new projects
and new opportunities to further the field, both as a researcher and an
organizer. He answered many questions of mine over the years and was very
helpful and influential in my work. Most of all I enjoyed his relaxed but
focused style and his ubiquitous sense of humor. It was always a pleasure to be
in his company. He will be sorely missed.
It is hard to imagine that he is no longer with us. I extend my heartfelt
condolences to his family.
Robin Graham
From Antoni Pierzchalski; Professor; one of Tom's co-authors;
former visitor with us at U of I.
Dear Friends, I think we are too sad to understand our loss.
Tom was a great mathematician, His achievements are high. More than 70 important
papers. Every differential geometer all over the world appreciate Tom's stature.
But, first of all, he was a great man.
Dear Tom, Thank you, thank you for everything! For your mathematics. For all
your results. For the complete characterization of the ellipticity: "Stein-Weiss
operators an ellipticity" in the J. Funct. Analysis (1997), your famous, great
paper.
It was always something mysterious in you doing mathematics: Deep understanding,
clarity, brilliant calculations, and the passion.
I had the honor and the pleasure of working with you a little, to discuss
mathematics, to cooperate. All your ideas are close to me and, I am sure, to all
of us knowing you.
Why that happened? We are trying to understand. A Short fragile life.
But you, Tom, you have gone too early....
Still, I am happy that I met you (many years ago in Denmark: it was Bent who
caused that) and then several times in Denmark in the US and in Poland. I am
happy that we spent some good time and became friends. You are one of the best
friends I have ever met. I am happy that I know your family. Your charming
Susanne and your wonderful girls: Sara and Eva. They are a part of you. The part
that will stay with us here on our further road.
And as usual,
Best regards,
Antoni.
I met Tom and Susanne in the early 1990's in Adelaide,
Australia.
Having some common interests we soon started email exchanges, began
collaborative work and developed a strong friendship. Over the years we visited
each other many times and I have very fond memories of BBQs and beers at the
Branson household. Tom was very proud of his wife Susanne and his two daughters
Sarah and Eva. He would tell me many stories of their successes and strengths.
Tom and I had a very free exchange of ideas. For me this was great source of
inspiration and his ideas greatly enhanced my research and my enthusiasm for
many mathematical directions. He was a great source of knowledge and always
ready answer questions regardless of his schedule.
I feel it is a tremendous honour to have worked with Tom and to have spent some
good time in his company.
I will seriously miss the chance to work with Tom, and I will miss his wit and
wisdom -- but what I will miss most is a great guy and a very best friend.
Rod Gover
I am very saddened to learn that Tom passed away on Saturday, actually during my
visit to Iowa. I feel so sorry for his wife, Susanne, whom I have met a long
time ago, and for the daughters, Sara and Eva, who I have unfortunately never
met. But I also feel very sorry for the Department, which has lost an
outstanding faculty. Tom was a close friend of mine, we were hired in the same
year, 1985, he built up the Geometry group and I was busy with the PDE group. We
shared many interests, and had common friends
With all my best wishes,
Friedmar Schulz
From Walter Seaman:
Tom Branson was respected all over the world for
his insights, originality and productivity in Mathematics. Those of us who
learned from him will greatly miss the clarity and effectiveness of his ideas in
differential geometry, and especially applications of representation theory to
that subject, and analysis of differential operators. So having Tom participate
in seminars and additional academic and administrative work was always a joy. In
addition to shouldering much more than his fair share of intellectual and
administrative work in mathematics, Tom also had a great sense of humor. In
seminars and meetings over the years I knew him he could always find just the
right double entendre or funny pop culture reference at the right time to keep
us all in stitches. Although he contributed a tremendous amount to the
mathematics community nationally and internationally, it was clear that Tom also
cherished his time spent with Susanne, Sara and Eva.
His untimely passing will be felt for a long time.
Walter
From William J. Ugalde; a former PhD student of Tom's, now Asst
Professor at Purdue University:
There are no words to express the sadness I feel now that Tom is not among us. I
have still so many questions to ask him!
More than a PhD advisor, Tom was a real mentor. A friend that was always there
to make me grow both as a mathematician and as a person. He always had the right
word of advice, and some times, the push I needed to get through. There is no
doubt about how important his contributions to mathematics are, and will be in
the future, since most of them are constant source of inspiration to many.
I hope his wife, daughters, family, and friends will find the comfort and the
courage to live our lives in a way that reflects Tom's passion for it. Deeply
sorry, but at the same time, extremely proud of having shared with Tom an
everlasting and enriching friendship as no other,
William J. Ugalde.
From Carlo Morpurgo; one of Tom's co-authors. [question/answer]
Dear Palle; this is Carlo Morpurgo, I visited you a while back. I am one of
Tom's collaborators, and I am shocked. Could you tell me how it happened, not
that this makes any difference!
Carlo.
Palle (reply): Thanks, Carlo;
We are still in shock here. It was a completely unexpected and sudden heart
attack. Despite Tom being athletic and in great shape, apparently a piece of
loose plaque from a main artery can travel to a smaller one, and block the flow
of blood to the heart. That is the best as I understand it (probably very
incompletely.) Tom had had a regular physical only weeks before, and no signs of
it were detected then. When tragedy struck (Saturday on the eleventh), Tom was
driving alone with his two little girls, Sara and Eva. An ambulance came, but it
was too late.
Regards,
Palle
PS.: Our dept website has more details, including info about an education fund
for Sara and Eva, now in 2nd and 3rd grade.
From Vincent Rodgers; Professor of Physics, the University of
Iowa.
Hi Palle, in physics Tom is also known for computing the conformal anomaly in
quantum gravity and the heat kernel asymptotics. I have attached the papers he
has written that have become part of the physics literature.
Sincerely,
Vincent.
PS. [Added by Palle!] The following might not be as widely known as I think it
should be: Tom (from math) and Vince Rodgers (from physics) organized an ongoing
workshop (physics and mathematics) which included among others student projects
(undergraduate and graduate). In some form or another, this Branson-Rodgers
project has now run for a decade. In his email message to me, Vince included a
list of fourteen papers by Tom and co-authors which relate to this branch of
Tom’s mentoring and interactive research activities.
PPS. Only a few days before Tom died, the math department had a one-day VIGRE-site
visit from the NSF where our department had a chance to highlight some of our
unique interdisciplinary outreach and mentoring projects here at Iowa. In the
afternoon VIGRE-meeting, Tom eloquently described this Branson-Rodgers project,
emphasizing the *vertical* nature of it.
Tom, the mathematician, the man, the friend and the father.
Since Monday morning, it has been so painful to realize and to accept. Tom has
deeply influenced my life. With him, I learned to push the limits of what would
concretely mean to have a clear and deep thinking, to take a huge distance from
things and events so that the essence could be touched.
During a discussion, when Tom starts to bat his eyes, it is the indication that
he got it, that he understands what was really going on. Then it was simply
exceptional and intense moments of life.
Mathematics, sports, nice food, philosophical and cultural discussions, family
and personal considerations, education, teaching and how to help young
mathematicians, were some aspects of life which we intensively shared.
Second order Conformal Covariants, Stein-Weiss operators and Q-curvature are
some higlights of his mathematical contribution in the field of Conformal
Geometry which had and continue to have big impact on research, both in
mathematics and mathematical physics.
The particularity of Tom's impressive research is the association of a physical
intuition and motivation, a deep knowledge of Representation Theory and
Differential Geometry together with an exceptional computational ability, both
theoretical and explicit based on computer programs.
Professionalism, pragmatism, deepness, clarity, generosity, definiteness,
intensity, originality, humour and insight are certain aspects of Tom's
mathematical contribution and of his personality.
Good bye Tom, my friend.
Oussama Hijazi.
I first met Tom in his algebra class in 1997 and I remember, in
the very first class, I was so much impressed by him, not just by his teaching.
Later, I found he's a differential geometer and my new life with him began.
He invited me to his world and I was overwhelmed by this truly knowledgeable and
wonderful man. I loved to chat with him through email and also very much liked
the way he wrote things even in his research papers. I bet I can tell whether if
a paper is written by him or not by reading first few pages. I liked the way he
walked on the street, too.
I always wanted to stay close to him for a long, long time and keep chatting
with him, keep watching him walking on the street. When I first learned that he
passed away, I was so sad and so upset at him for the first time since I met
him. I guess I didn't like to ask him many questions for some reason. But this
time, I kept asking him why he had to die. I wanted him to come to my dream and
answer this question.
I believe that he tried his best to save his life because I know he loved his
wife Susanne and two little girls Sara and Eva so much.
I know I won't get email from him anymore but I believe we'll figure out a way
to communicate with each other until we meet again.
Doojin Hong
From Carlo Morpurgo, one of Tom's collaborators (trace
inequalities, conformally invariant operators, Zeta functions...)
I first got in touch with Tom in 1989, and for a good while most of our
interaction was by email.
Initially, I had contacted him about a second variation formula I had found,
while working on my PhD thesis.
I was struck by his mathematical knowledge, but especially I was touched by his
kindness and availability for interacting with me; given the way our
communication had started....kind of out of the blue.....
After I completed my PhD, I emailed him again about another strange formula I
had found, and his response was: "This is really intriguing!" I still cherish
that particular moment.
From then on, Tom was one my absolute references in my research which was
heavily based on his work on conformally invariant operators, and related
inequalities for the log-determinant.
His deep knowledge of the subject and his ability and patience in explaining it
were clearly outstanding.
But most importantly, Tom was someone I trusted, both on a personal and a
mathematical level.
I was very at ease with him.
More recently, Tom was involved with me and Luigi Fontana on a very promising
project, which he himself started; we were all very excited about it, and still
are. I promise you Tom: it WILL be finished!
We had plans for the summer, maybe he would have come to Italy. I was looking
forward to the possibility of seeing there also Susanne, Sara and Eva, and
having all of them as our guests in Milan.
I am deeply, deeply saddened by this loss, and I will miss him immensely.
My warmest thoughts to Tom's family.
Ciao, Tom!
Carlo.
From one of Tom's current PhD students, Alfredo Villanueva:
I am deeply saddened to learn of Professor Branson's passing; my
condolences to his family, to his friends, and to all who felt close to him.
It took me a while to comprehend and accept what has happened. He was my mentor
and also one of the best professors I have ever had. We have been working for a
few years, and I have been inspired by his deep knowledge and his mathematical
insight. Professor Branson, I would like to thank you for your friendship,
advice, mentoring, and all the help you gave me.

I knew Tom from way back, and our families are close:
Christmases, Thanksgiving etc (and a shared language that no one understands,
Danish!)
After the sad news about Tom, many of us cried. And lots of friends wrote in
with reminiscences.
The Branson siblings, six brothers and a sister are from La Crosse Wisconsin.
Although now scattered around, they all arrived here immediately on the fateful
Saturday. They stayed in town for a week, helping and supporting Susanne, Sara,
and Eva; and each other.
Facts: The Branson siblings lost their mom early, and they grew up taking care
of one another. What a team!
I discerned a pattern. The older Jim (now a physics professor) adapted to one
role, and Tom grew into the cheerful, supportive and generous friend we have all
come to know. A wonderful colleague: a sunny disposition, and an inexhaustible
supply of jokes when we were depressed.
Susanne and I both grew up in little Denmark where it rains all the time!
Walking on our way to the physics department here in town, or on our way to a
dinner, I would complain about the Iowa City drizzle. --- "Palle, in Denmark,
this is called a *dry* day!" Tom shot back. By magic, suddenly, the rain didn't
matter!
Trivia: As a boy, Tom was a spelling bee! To increase his allowance, he worked
for publishers doing copy editing. Jim reports that Tom did it to perfection
(not surprisingly); and incredibly fast!
Susanne: "Bless you all and please, live life to its fullest!"
Palle.
From Palle Jorgensen and Mike Eastwood:
I am corresponding a lot with one of Tom's co-authors who is a very
distinguished mathematical physicist and geometer, Mike Eastwood (a recent
Annals paper). Here is a sentence from his last letter which confirms the value
of Tom's website:
His website is an enormously useful resource, especially for his past articles
(e.g. the one where Q- curvature is introduced, which you can only otherwise buy
from Seoul).
All the best,
MikE
It is invaluable for students, for workers in the field, so I hope it can be
preserved. In addition, it contains some historical records that can't be found
elsewhere.
And in addition the geometry community involved with the three-year NSF funded
conference series started by Tom, they tell me that they rely heavily on Tom's
website as well. The Mid-West Geometry conference series!

Palle
From Bent Orsted, Professor of Mathematics, Aarhus University:
Kaere Palle,
Jeg har skrevet et lille stykke om
Tom - maaske kunne du saette det paa hjemmesiden
med "recollections from colleagues"? Jeg sender
det ogsaa nu til Susanne. Det er selvfoelgelig kun
en draabe i havet, der var meget mere at sige.
Tak og venlig hilsen,
Bent.
PS. Jeg vil ogsaa skrive tilbage vedr. Mike's
udmaerkede artikel.
PPS. Jeg haaber alt gik OK til begravelse osv.
I first met Tom at MIT; this was in the late seventies and I had
gone there to write a thesis under Irving Segal,who also became Tom's Ph.D.
advisor. We were both interested in Segal's theories of the universe, wave
equations, quantum fields, particles etc. -with the added excitement of
astronomical (and controversial!) consequences: redshift and background
radiation. Little did I know at the time, that Tom Branson would become a very
good friend, mathematically and otherwise; that we would meet many times over
the coming years, and that our lives and work would become an intertwinedpattern
in time and space, for which I am thankful - and sad that it could not continue.
It has been a priviledge for me to work with Tom, and I always admired his
skills for logic and for carrying out long calculations. This was not merely
bookkeeping; with Tom it was part of the mathematical art to see and hear what
precision and logic would squeeze out of those expressions, always keeping the
structural perspective. He just really enjoyed mathematics. Not that he did not
enjoy other things as well - he would apply himself with the same cheerful
attention to anything from sports, language (learning Danish) and knowledge of
music to the most important: family life with Susanne, Sara and Eva.
It is a testimony to Tom's gregarious nature that he worked with so many
colleagues - and that so many appreciated his friendliness and humour. I do not
know how many times he
could make us laugh, always with dry jokes, and with a never-ending supply of
insights and quotes from the world of entertainment (say from just one
favorite, the "rumble in the jungle", i.e. the 1974 heavyweight fight in Zaire
between Muhammed Ali and George Forman, where Ali reclaimed the title, warming
up with: "I handcuffed lightning and put thunder in jail, I am so bad I make
medicine sick!").
Later, George Forman, getting on in years (as ourselves) would be a theme of
some consolation, when a sports reporter would describe the aging (still
fighting) Forman: "Well, old George might be slow, but when he hits you, you are
the deadest body in the cemetery".
Tom was increasing his activities it seemed on all fronts, both the research,
the international cooperation, and the organization of conferences. He also went
to meetings in the NSF, where his opinions were important in evaluating grant
proposals.
For myself, I shall always remember Tom's friendship, how he was a dear guest in
our family, the American uncle for my kids, in particular for my son Peer - and
how we now miss him, now that it is hard to
comprehend, now that logic stops, perhaps in the words of William Blake:
To see the world in a grain of sand,
and heaven in a wild flower.
To hold infinity in the palm of your hand,
and eternity in an hour.
To the memory of Thomas P. Branson.
Bent Orsted.
From Professor Rafe Mazzeo, Stanford University:
Dear Palle,
I heard about this tragic event just a few days after it had happened, from
Larry Peterson. I've felt very badly ever since -- I counted him as a good
friend and we had been getting to know each other much better just in the last
few years, so this was really a blow for me. I hope his wife and children, whom
I had never met, are doing OK and I am pleased to see that there is an
educational fund for them -- I will surely donate!
I'm also very pleased to see that you are organizing this conference; please let
me know if there is anything I can do to help, but in any case I'll do my best
to come.
Best wishes,
Rafe Mazzeo
From Professor Bill Beckner, University of Texas, Austin.
Palle,
I was very sad to learn the news about Tom Branson. Tom was a great person, and
I still remember well my visit with him in 94 at Iowa City. Tom was an original
mathematician with a distinctive vision, and the impact of his mathematics,
especially on geometric analysis, will only increase with time.
As a friend he will be missed by many people, and I wish only the best for his
wife and daughters in this difficult moment.
--Bill
I was just told by a friend about this sad and so unexpected news.
It was hard to believe it at first. Tom was so full of life. Now I am reading
the "Reminiscences from Colleagues" section of the memorial webpage and I see
how much he will be missed and by so many.
I met him several times, mostly at various conferences in Europe. In January of
2004 we were in Srni for a couple of weeks lecturing together.
On more than one occasion we met in Vienna. I have learned a lot from him.
It was always a pleasure to talk to him about anything: math, politics, life...
I will miss him.
Kris Galicki
From Collin Bennett, one of Tom's co-authors.
I can't tell you how sorry I am to hear about Dr. Branson.
He was a great person and seemed to genuinely care about everyone. He repeatedly went out of his way for me, but he seemed to do that with a lot of people. I always thought of him as a friend, but he treated everyone the same way, so maybe he wasn't my friend, but rather everyone's.
I don't think an epitaph changes how someone is remembered, so I don't really think that there is much to say about someone in a situation like this. But if I knew that some words were going to be the last ones he heard from me, I would have wanted them to be "Thank you."
Collin Bennett.
In planning for the conference next year at the University of Iowa
http://www.math.uiowa.edu/MGC2007/ ,
Palle asked one of Tom’s recent co-authors and collaborators, Rod Gover, University of Auckland about some trends and directions in Tom’s work:
PJ: Q-curvature
RG: Yes, conformal geometry and Q-curvature was certainly a big focus for Tom over much of his career including his recent work.
PJ: mathematical physics: e.g., functional determinants of conformal operators on 4-manifolds
RG: -- for Tom at least -- I don't think the emphasis (albeit by way of example) on 4-manifolds is so relevant. Certainly Tom was interested in applications of the functional determinant and Polyakov formulae in any dimension that he could get his hands on. Explicit results were most abundant in dimension 4 simply because it was essentially the simplest case. Tom’s view were more general: "spectral invariants"!
PJ: PDE and geometric measure theory
RG: Tom was recently very interested in the use of prolonged systems in certain PDE problems (e.g. overdetermined PDE, higher symmetries of operators). Since it was a recent interest he had only limited work in this direction -- but it was certainly one of his new focuses. In fact he has a PhD student working on such things.
PJ: Your work with Tom?
RG: For the record, the joint work that Tom and I produced mainly concerned some new ways of blending elliptic theory with some of the modern tools of conformal geometry. The aim of this was to produce new global conformal invariants and nonlocal invariant operators. Among the results were operators which generalize Q-curvature, elliptic detour complexes and a type of conformal Hodge theory. The biggest unfinished project (I have about 5 or 6 open projects with Tom) is the construction and study of the functional determinant (or torsion) of the elliptic detour complexes.
PJ: Kengo Hirachi and Tom?
RG: There was certainly plenty of common interest -- especially in the direction of Q-curvature.
Speaking of 'ceiling', here two more Tom-stories.
(1) *Roof over our heads*:
A recollection from a math meeting we both went to a few years ago in
Philadelphia (Bent was there too from Denmark; but Gestur was stuck in a God
forsaken airport!); it was back when I was still on crutches (although my
crutches had been sent to a different hotel!):
Tom and I shared a hotel room, but we must both have been late getting our hotel
reservations. When it dawned on us, Tom, with a straight face shot back: "Oh,
well, we can always sleep under a bridge!"
We did get the room!
(2) *Institution*
At the reception, Tom had just introduced Bent to a big shot (PM) from France.
Polite smiles followed, some silence, and perplexed faces!
Finally PM asked Bent: "What institution are you from?"
Bent (with his poker face) : "Denmark!"
Regards
Palle
PS.: Palle: Palle Jorgensen; Bent: Bent Orsted; Gestur: Gestur Olafsson. And one
more name: Paul Malliavin.
