Department with Strong Showing at JMM Seven faculty members and two students represented the Grinnell Mathematics and Statistics Department at this year's Joint Mathematics Meeting in Boston, January 4-7, 2012. The Joint Mathematics Meeting is an annual meeting of the American Mathematical Society (AMS) and the Mathematical Association of America (MAA). It is the "Largest annual mathematics meeting in the world" and had over 7000 attendees this year. Alice Nadeau '13 and Bingxi Wu '13 presented the poster Multiplicative Partitions during the MAA Undergraduate Poster Session.
The Mathematics and Statistics Department had a very active summer research program under the College's Mentored Advanced Projects. Six faculty offered seven projects which involved fourteen students.
Professor Marc Chamberland worked with three MAP students during the summer of 2011: Colin Johnson ‘13, Alice Nadeau ‘13, and Bingxi Wu ‘13. Their project was to understand the structure of multiplicative partitions.
The scholarly activity of the mathematics and statistics faculty was showcased at numerous conferences over the summer.
Professor Christopher French cowrote an article, "Hankel Transforms of Linear Combinations of Catalan Numbers" with math majors Michael Dougherty, Benjamin Saderholm, and Wenyang Qian, all math majors in the class of 2012. The article appeared on April 20 in the Journal of Integer Sequences, Vol. 14 (2011), Article 11.5.1. In this paper, the authors consider the result of applying a certain operation called the Hankel Transform to certain sequences of numbers obtained in a natural way from the famous Catalan number sequence.
The Grinnell College Putnam team placed 46th out of 546 teams from across the U.S. and Canada. The annual exam took place in December with 16 Grinnell students among the 4296 students who took the exam. Grinnell College had four students score at least a 20:
Professors Shuman, Blanchard, Chamberland, T. Moore, and E. Moore take advantage of spring recess to attend workshops, do research, and give lectures.

Marc Chamberland and Patrick Lopatto (a Grinnell High School student) published the paper "Formulas for Odd Zeta Values and Powers of Pi" which appeared in the electronic Journal of Integer Sequences (Vol. 14, Issue 2, article 11.2.5). Values for the Riemann zeta function at odd values greater than one do not seem to have a closed form. A decade ago, the Canadian mathematician Simon Plouffe experimentally found some formulas to represent these numbers using quickly converging infinite series.
