Speaker: Prof Frank Calegari (Northwestern)
Title: Reciprocity and the Langlands program
Date: Friday, 6 May, 2010
Time: 14:30 Venue: Carslaw 175, University of Sydney
Abstract: How much does the cohomology of an algebraic variety tell us about the variety itself? The answer, at least according to a conjecture of Tate, is quite a lot. In this talk, I will try to outline the relationship --- mostly conjectural --- between algebraic varieties, their cohomology, and a special class of functions (L-functions) generalizing the Riemann zeta function.
We will depart from the 2nd floor of Carslaw at 1 PM for lunch at the Grandstand (together with folks from the algebra seminar). Please let me know if you are planning to attend lunch so that I can book an appropriate size table.
