SUMMARY:A tribute to Professor Ellis Cumberbatch (1934-2021)
DESCRIPTION:Title: A tribute to Professor Ellis Cumberbatch (1934-2021) \nAbstract: The math colloquium on December 1st will be devoted to remembrances of our beloved CGU colleague Professor Ellis Cumberbatch\, a pillar of the Claremont mathematics community\, who passed away in September. Three brief talks by his friends and collaborators\, Professor John Ockendon (University of Oxford)\, Dr. Henok Abebe (Sandia National Labs)\, and Professor Asuman Aksoy (Claremont McKenna College) will be followed by informal reminiscences by any of the attendees who wish to share their stories involving Ellis. You are welcome to have your glass of wine\, beer\, or other drink so we can have a virtual toast in his memory. This zoom session will be recorded so it can be shared with those who wish to watch it later. \n \n \nCGU’s remembrance of Prof. Cumberbatch can be found here.

SUMMARY:Difference sets in higher dimensions (David Conlon\, Cal Tech)
DESCRIPTION:Let d >= 2 be a natural number. We determine the minimum possible size of the difference set A-A in terms of |A| for any sufficiently large finite subset A of R^d that is not contained in a translate of a hyperplane. By a construction of Stanchescu\, this is best possible and thus resolves an old question first raised by Uhrin. Joint work with Jeck Lim.

SUMMARY:Where do Putnam problems come from? (Prof. Andrew Bernoff)
DESCRIPTION:Title: Where do Putnam problems come from? \nSpeaker: Andrew Bernoff\, Department of Mathematics\, Harvey Mudd College \nAbstract: The William Lowell Putnam Exam is the preeminent mathematics competition for undergraduate college students in the United States and Canada. I recently finished a three year stint on the competition’s problem committee. This talk is a personal reflection on where Putnam problems come from. I’ll discuss three problems which can loosely be described as: \n\na mathematician’s viewpoint on axe throwing\,\na model for how chickens establish a pecking order inspired by a high school math competition and a subsequent tweet by Jordan Ellenberg\, and\na covering problem that arose from a generalization of several previous Putnam problems viewed through the lens of a mathematician obsessed with the Fourier transform.\n\nI’ll close with some observations about best practices and pitfalls to avoid when constructing an exam whether it be for a class or a competition. \n\nAndrew Bernoff is a Professor of Mathematics at Harvey Mudd College. While his research concentrates on using dynamical systems methods to understand experiments and natural phenomena\, he has a longstanding interest in recreational mathematics and problem solving. As an undergraduate at MIT he ran the first Integration Bee\, a tradition that has now continued for over four decades. More recently he just finished a three year stint on the William Lowell Putnam Exam’s problem committee.
