Titel: The infinitesimal structure of representation varieties

Abstract:
A representation of a group G is a homomorphism to the general linear group of a field. The collection of all representations of G can (more or less) be made into a space, called the representation variety of G. I will discuss joint work with Akshay Venkatesh on the structure of such varities in infinitesimal neighborhoods of points and, time permitting, relations to number theory.
