Pure Mathemetics 3/08/04

Speaker: Professor Bill Casselman (University of British Columbia)
Title: "Chipping away at convex polyhedra"
Date: Friday, 6th August, 2004
Time: 2:00 pm
Venue: Carslaw Building, Room 373, University of Sydney

Abstract:
Results of M. N. Ishida, M. Brion, M. Vergne, and myself about convex
polyhedra in ordinary Euclidean space were motivated, at least for me,
by work of Jim Arthur on automorphic forms. I will explain the
original results, which are very elementary, as well as give some idea
of the relationship with Arthur's work. One application is a formula
due to Brion and Vergne for the Fourier transform of the
characteristic function of a bounded convex polyhedron, related to the
classical formula of Maass and Selberg about Eisenstein series.

Special Lecture by Professor Bill Casselman

4000 Years of Mathematics in Images

Tuesday 3 August at 5.30 in the
Eastern Avenue Lecture Theatre (near City Road)
The University of Sydney

Professor Bill Casselman is the Graphics Editor for the Notices of the
American Mathematical Society and regularly produces the cover art and
other mathematical images for the Notices.

On Tuesday 3 August at 5.30, Professor Casselman will present a
selection of photographs and other images that he has put together over
the past several years, of mathematical artefacts ranging from about
1800 B.C. to the early twentieth century. Many of them will be concerned
with Pythagoras' Theorem.

The talk should be intelligible to anyone who has liked high school
geometry.
