GALOIS REPRESENTATIONS AND AUTOMORPHIC FORMS SEMINAR

Topic: Vanishing Theorems for Torsion Automorphic Sheaves

Speaker: Kai-Wen Lan

Affiliation: Veblen Research Instructor; Princeton University/School of Mathematics

Date & Time: Thursday December 9th, 2010, 2:15pm - 3:15pm

Location: S-101

In this talk, I will explain my joint work with Junecue Suh on when and why the cohomology of Shimura varieties (with nontrivial integral coefficients) has no torsion, based on certain new vanishing theorems we have proved. (All conditions involved will be explicit, independent of level, and effectively computable.)
