"Galois Representations"

The absolute Galois group of the field of rational numbers is a fundamental object of study in number theory. I will begin by giving a tour of the representation theory of this group, with an emphasis on representations in characteristic p. In the second half of the talk I will describe my recent work with Gee, Liu, and others on generalizations of the weight part of Serre's conjecture on two-dimensional mod p Galois representations.

Refreshments will be served in MC 5046 at 3:30 p.m.

Everyone is welcome to attend.
