MATHEMATICS
AND STATISTICS DEPARTMENT
The academic year 2004–2005 proved to be another successful and
exciting year for the department. The excellence of the faculty continues to be
recognized nationally. This year Edward Burger was awarded the 2004 Chauvenet
Prize—the oldest prize given by the Mathematical Association of
America.
We are very pleased to welcome two new members of our department. Mihai
Stoiciu, who studies mathematical physics, will be coming from the California
Institute of Technology. Our newest statistician, Carsten Botts, will be
joining us from the University of Florida. We are excited about their arrival.
Also joining us for the fall semester will be our own Charlie Stevenson. We
welcome back Colin Adams and Tom Garrity from their sabbatical leaves. Tom will
return to lead the College’s PET program for new faculty. While we look
forward to these additions, we also say some sad goodbyes. Going on leave this
coming year are Dick De Veaux, who will spend the year in France, Satyan
Devadoss, who will be visiting Ohio State University, and Stewart Johnson (for
the spring term) will be pursuing his research here in Williamstown. We say
goodbye to Perry Susskind, who was an active and lively visitor this year from
Connecticut College. Finally, we acknowledge an important milestone in our
department’s history. Victor E. Hill IV, Thomas T. Read Professor of
Mathematics, completed his regular teaching at Williams this year and will
retire in June 2006 after 40 years on the Williams faculty. Professor
Hill–your colleagues and your incredibly long list of students all salute
you and thank you for your many years of dedicated and inspirational
teaching.
We are very proud of the accomplishments of our graduating seniors. The
Rosenberg Prize for outstanding senior was awarded to Matthew Spencer ’05.
Elizabeth Landis ’05 and Emily Tomassi ’05 received the Goldberg
Prize for the best colloquia. Stephen Moseley ’05 was awarded the Morgan
Prize for Teaching and/or Applied Mathematics, and Ivan Manolov ’05 was
awarded the Robert M. Kozelka Award, while Matthew Spencer ’05 won the
Witte Problem Solving Prize. Ashok Pillai ’05 was applauded for the
highest colloquium attendance (he didn’t miss one!), with Matt Spencer and
John Mugno ’05 coming in as impressive runnersup.
The department is particularly appreciative of the dedication and hard work
of the members of the student advisory board, SMASAB (Students of Mathematics
and Statistics Advisory Board), each of whom were heavily involved in the
faculty hiring process, in addition to organizing the department’s
advising Ice Cream Socials and Pi Day. The members of SMASAB were Kathleen
Beutel ’06, John Chatlos ’07, Diana Davis ’07, Kathryn Lindsey
’07, Neil Mendoza ’07, John Mugno, Jordan Rodu ’05, Todd
Shayler ’06, Matt Spencer ’05 and Ben Steinhurst ’05. Our
department Senior Advisors were Elizabeth Landis ’05 and Matt
Spencer.
Some senior mathematics majors at the department’s opening ceremonies
for the 20042005 year.
Beyond our traditional Ice Cream Socials, this year we had a special pizza
lunch in September for all first year students enrolled in one of our courses
and, in October, a special dinner (with music) at the Log for all secondyear
students in our department. We also enjoyed a wonderful Pi day (March
14–3.14) with a FamilyFeud style game show and tattoos. During Reunion
Weekend, Professor Morgan organized the first Department Reception to welcome
back our alums. It was a huge success with many classes returning to meet their
old professors and enjoy one of our famous “teas”.
All of the members of the faculty had a busy and productive year. Their
individual highlights and achievements are given below.
Professor Colin Adams was on leave for the 20042005 academic year. In
Vancouver in summer 2004, he lectured for a special course on knot theory for
graduate students from around the world. He spent the academic year in
Williamstown, with a variety of trips to give talks and consult with colleagues.
He continued work on a textbook on applied topology due to appear next January.
He spent most of his research time trying to understand the properties of
quasiFuchsian surfaces in hyperbolic 3manifolds.
Professor Ollie Beaver was on leave in the fall of 2004. While on leave,
she returned to her former research in quantum logics. In January, she attended
the Joint Mathematics meetings held in Atlanta, Georgia. At Williams, she
returned to active participation as a trustee in the Robert L. Gaudino Memorial
Fund. Beaver continues to teach in and coordinate the mathematics component of
the Summer Science Program.
Professor Burger continued his research in number theory. In August, he
published his fourth book, Making Transcendence Transparent: An Intuitive
Approach to Classical Transcendental Number Theory, coauthored with Robert
Tubbs, with SpringerVerlag. He used his text in a new Senior Seminar course he
offered in the fall. Also in the fall, he was the thesis advisor for Ashok
Pillai ’05. In April, he published A Tail of Two Palindromes in
The American Mathematical Monthly.
Burger also pursued some larger projects. With Michael Starbird, he
published the 2^{nd} Edition of The Heart of Mathematics: An
Invitation to Effective Thinking (Key College Press and SpringerVerlag) and
completed a generalaudience trade book entitled Coincidences, Chaos, And All
That Math Jazz (to be published by W.W. Norton & Company this summer).
He continued to create mathematics videos for a series of texts to be published
by Holt, Rinehart & Winston.
The Mathematical Association of America awarded Burger the 2004 Chauvenet
Prize. He was also named to the Editorial Board of AK Peters Publishing and as
a trustee of the Educational Advancement Foundation. His precalculus videotext
with Thinkwell was recently nominated for the 2005 Association of Educational
Publishers Distinguished Achievement Award.
Professor Burger gave numerous lectures at various conferences and
institutions including invited addresses at the National Academy of Sciences and
the Boston Public Library.
Professor Satyan Devadoss finished his third year here at Williams College.
In summer 2004, he supervised his team of SMALL summer students in research on
computational geometry. In particular, they looked at compatible triangulations
and homotopy of cartograms.
Professor Devadoss continued his research in configuration spaces, along
with work in mathematical origami. Along with giving talks at Williams, such as
Sigma Xi in fall 2004, he was invited to speak at MIT, Calvin College, Boston
University, as well as at some conferences.
Professor Devadoss worked with John Mugno as his thesis advisor on
jugglings and links. He also coorganized (with Professor Pacelli) the Hudson
River Undergraduate Math Conference this year at Williams.
De Veaux continued his research on data mining and gave presentations
throughout the US and the world, including a keynote address at the SPSS
Users’ Conference in Las Vegas and an invited address at the annual
meeting of the Northern New Jersey Chapter of the American Statistical
Association. He also presented papers at the
International Conference on Technology in Collegiate Mathematics (ICTCM) in New
Orleans, and the PacificAsian Conference on Knowledge Discovery and Data Mining
(PAKDD) in Hanoi, Vietnam. He continued his participation as a member of the
National Academy of Sciences Committee on Assessing Behavioral and Social
Science Research on Aging.
Professor Richard De Veaux and coauthors Paul Velleman of Cornell and Dave
Bock published the second edition of their introductory Statistics
textbook.
Professor Thomas Garrity has continued his research in geometry and number
theory. This past year he has been on sabbatical as a Fellow of the Oakley
Center for Humanities and Social Sciences, working on issues involving the
philosophy of mathematics. His survey of the basic literature in algebraic
geometry and differential geometry has appeared in Using the Mathematical
Literature. His review of John Adam’s Mathematics in Nature
has appeared in the Mathematical Intelligencer. In August, in Providence
RI, he lectured on how to give a lecture at Project NEXT, a mentoring program
for new faculty in mathematics. He is looking forward to returning to the
department and to teaching.
Victor E. Hill IV, Thomas T. Read Professor of Mathematics, completed his
regular teaching at Williams in January and was on leave in Oxford for the
spring semester, where he continued his research on the mathematical analysis of
changeringing. He will retire in June 2006 after 40 years on the Williams
faculty.
Professor Johnson continues his research in dynamical systems, modeling,
and optimal control with a focus on optimal periodic switching strategies. He
is interested in small rapidly switching cycles that approximate probabilistic
behaviors. Professor Johnson has demonstrated the generic existence of such
cycles in high dimensions. Professor Johnson is continuing to explore normal
forms and the types of behavior possible when the cycles degenerate.
Professor Johnson supervised two theses this year. Johnson proved the
existence of approximating twocycles, but his proof was not constructive.
Jordan Rodu ’05 completed a thesis demonstrating the normal form for
switching cycles in three dimensions. Johnson and Rodu are preparing their
results for publication. Stephen Moseley ’05 completed a thesis on the
high dimensional dynamics of helical structures representing idealized collagen
molecules. Moseley investigated formation dynamics and demonstrated parameter
regions for stability of these structures.
Professor Johnson continues as a statistical consultant for research
conducted at Neurological Consultants of Bennington by Dr. Keith Edwards,
’69. This research is an ongoing effort to establish the safety and
efficacy of Galantamine as treatment for dementia with Lewy bodies.
Professor Johnson remains active in the college wide Quantitative Studies
program. The program has been successfully expanded to include two classes at
the precalculus level. Math 102 prepares students for calculus and general
science courses, and Math 101 prepares nonscience students for classes in
economics, psychological statistics, and life after Williams.
Professor Bernhard Klingenberg worked as a biostatistician in the
statistical methodology unit of Novartis Pharmaceuticals in Basel, Switzerland,
from June to August 2004. His paper with Alan Agresti on “Multivariate
Tests Comparing Binomial Probabilities, with Application to Safety Studies for
Drugs” was accepted by The Journal of the Royal Statistical Society
Series C, (Applied Statistics) in August 2004. In November 2004, he
was invited to give a presentation on “Regression Models for
DiscreteValued Time Series Data” at Cornell University in Ithaca, NY. He
received a young researcher scholarship to attend a conference on Longitudinal
Data Analysis in Florida in January 2005 and present a poster titled
“Global Tests for Multivariate Binary Data”.
He also served as a referee for manuscripts submitted to The Journal of
the Royal Statistical Society, Series B, The Journal of Pharmacokinetics
and Pharmacodynamics and to Statistical Modeling.
In January 2005, Professor Susan Loepp attended the annual Joint
Mathematics Meetings in Atlanta where she especially enjoyed the special session
in Commutative Algebra. This year Loepp’s paper coauthored with former
thesis student Pippa Charters ’03 appeared in the Journal of
Algebra. In the paper, Charters and Loepp characterize completions of local
rings with a semilocal generic formal fiber. Loepp served as a reviewer for
The American Mathematical Monthly, Communications in Algebra, and The
Journal of Algebra. In June, Loepp and William Wootters (Physics) gave a
Alumni Reunion Lecture based on the course they teach and the book they are
writing on “Protecting Information.”
Professor Frank Morgan had nine publications appear and has seven others in
process, including a joint paper with his 2004 honors thesis student Jonathan
Lovett. He is completing two texts for use in Williams courses on Real Analysis
and Applied Real Analysis, both scheduled to appear in 2005.
Morgan has given a dozen talks this year, including a talk on Family
Weekend on “Soap Bubbles and Mathematics,” replete with
demonstrations, explanations, and prizes.
He is directing the “SMALL” undergraduate research project and
organized a SMALL reunion at the MathFest in Providence last summer, at which a
dozen SMALL alums gave talks, followed by a banquet at Kabob and Curry. His
SMALL Geometry Group, including Elizabeth Adams ’06, Diana Davis
’07, and Michelle Lee ’06, is studying bubbles in Gaussian space.
In June, each group member is speaking at the Mathematical Association of
America (MAA) meeting at Bates, where Morgan is giving the invited address. In
August, they will join other SMALL groups in speaking at the MAA MathFest in
Albuquerque. This year a joint paper of his 1998 and 2000 Geometry Groups
appeared in the Journal of the Australian Mathematical Society.
Last fall, Professor Allison Pacelli introduced a new interdisciplinary
course for nonmajors at Williams called Mathematics and Politics: Voting,
Power, and Conflict. She also taught a new winter study course called
Pilates: Fitness, Philosophy, and Physiology.
Pacelli continued her research in algebraic number theory, and has had
papers accepted for publication by the Canadian Mathematical Bulletin and
the Journal of Number Theory.
Pacelli gave two Science Lunch talks at Williams, a faculty seminar in
February, and a talk at the Hudson River Undergraduate Mathematics Conference in
April. She also gave a special family weekend mathematics lecture in October.
In addition, she was invited to speak at the Brown University Undergraduate
Mathematics Seminar, the ColbySawyer College Department of Natural Sciences
Seminar, the Capital Region Algebra and Number Theory Seminar, the Association
for Women in Mathematics’ Workshop at the Joint Meetings, the University
of Rochester Number Theory Seminar, the Centre for Information Security and
Cryptography Discrete Math Seminar at the University of Calgary, and the
Mathematics Department Annual Awards Day Ceremony at the University of
Connecticut.
During the year, Pacelli advised the senior honors thesis of Matthew
Spencer ’05. They are currently writing up the results for publication.
She also acted as research mentor for a high school student who was named a
semifinalist in the Intel Science Talent Search for his work with polygonal
numbers. During the summer of 2005, she will advise the SMALL research group on
algebraic number theory.
Pacelli coorganized (with Professor Devadoss) the twelfth annual Hudson
River Undergraduate Mathematics Conference (HRUMC), which was held at Williams
this spring. The conference was a big success with a record number of over 230
talks, and 500 students and faculty attending from colleges across the
northeast. Ken Ribet gave the keynote address on his involvement in the proof
of Fermat’s Last Theorem.
Cesar Silva taught calculus courses in the fall and a tutorial in ergodic
theory, his area of research, in the spring. He is currently writing a book in
ergodic theory, a preliminary version of which was used in his class.
He published a paper with John Bryk ’02 in the American
Mathematical Monthly, and submitted another paper with A. Danilenko.
A paper with Sarah Iams ’04, Brian Katz ’03, Brian Street
(Virginia ’03), and Kirsten Wickelgren (Harvard ’03) describing the
results of SMALL ’02 was accepted for publication in Colloquium
Mathematicum. In summer ‘04, he supervised the SMALL research group
in ergodic theory consisting of C. Dodd, P. Jeasakul, P. Jirapattanakul, D.
Kane, B. Robinson, and N. Stein.
In May 2005, he organized a conference on padic dynamics at Wesleyan
University with Rob Benedetto (Amherst), and Mike Keane (Wesleyan). This was
funded by grants from the Mellon Foundation and the National Science Foundation.
He also was a referee for several journals.
Kristopher Tapp led a team of four undergraduates, who researched the
curvature of Lie groups and presented their discoveries at the national meetings
in Providence. He completed an undergraduate textbook titled Matrix
Groups (to be published this summer by the American Mathematical Society).
He spoke in William’s Physics seminar, motivated by an overlap between his
most recent research interests and particle physics. He also spoke at Dartmouth
College, visited a collaborator in Philadelphia, and will attend a conference in
Muenster, Germany this summer.
