Description:

We will give an introduction course to the research field called Geometric Langlands Theory (GLT).

Roughly speaking, GLT is the analogue of the classical Number-theoretical Langlands Theory under the function field analogy, but the mathematical structures studied in GLT are often “1-categorical level higher” than its number-theoretical counterpart. Typical such structures include: sheaves on the moduli stack of G-torsors or \check{G}-local systems, categorical representations of the loop group LG, sheaves on the Iwahori-Hecke double quotient, e.t.c..

We will introduce the main results and conjectures, as well as the guiding philosophy in this field. The goal is to provide enough preparation for people interested in this field to read new research papers.


Prerequisite:

Basic algebraic geometry, category theory, representation theory
