Spring 2018: Seminar on the Langlands Program
This is a seminar class on the Langlands program understood in a broad sense, covering topics ranging from number theory to quantum field theory, including, but not limited to, the following:
class field theory
Artin L-functions and Hecke L-functions
Tate's thesis
representation theory of real and p-adic groups
local Langlands correspondence
modular forms and automorphic representations
L-functions of elliptic curves and modular forms
Fermat's last theorem and modularity theorem
motives and special values of L-functions
Langlands functoriality and trace formula
Ngo's fundamental lemma
Drinfeld's shtukas
V. Lafforgue's global function field Langlands
geometric Satake equivalence
non-categorical geometric Langlands
ramified geometric Langlands
local geometric Langlands
Betti geometric Langlands
Langlands duality and 2-dimensional conformal field theory
Langlands duality and 4-dimensional N=4 supersymmetric gauge theory
In the first few lectures, the instructor explains how some of these topics fit into a big picture. For the remainder of the term, each participant gives a few talks on topics chosen in discussion with the instructor. One aim is to learn how to give a good expository talk. The instructor will also give a series of talks on topics of interest for the audience.
Disclaimer: The instructor is not an expert on most of the suggested topics!
