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 runners-up.
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.

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 second-year students in our department. We also enjoyed a wonderful Pi day (March 14–3.14) with a Family-Feud 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 2004-2005 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 quasi-Fuchsian surfaces in hyperbolic 3-manifolds.
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 Springer-Verlag. 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 2nd Edition of The Heart of Mathematics: An Invitation to Effective Thinking (Key College Press and Springer-Verlag) and completed a general-audience 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 video-text 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 co-organized (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 Pacific-Asian 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 co-authors 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 change-ringing. 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 two-cycles, 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 pre-calculus level. Math 102 prepares students for calculus and general science courses, and Math 101 prepares non-science 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 Discrete-Valued 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 co-authored 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 non-majors 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 Colby-Sawyer 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 semi-finalist 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 co-organized (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 p-adic 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.
