Content:
Moduli spaces of shtukas serve as analogues of Shimura varieties over function fields of positive characteristic. They are used with great success in the construction of a global Langlands correspondence for reductive groups by V. Lafforgue.
In the first part of the course I will introduce moduli spaces of shtukas (and related objects like Drinfeld modular varieties) and explain how they are function field analogues of Shimura varieties. We then continue to look at automorphic representations in particular in the function field setting.
In the last part I want to explain some of the ideas that go into Lafforgue's construction - at least in the GL_n-case.
Literature:
For the first part of the course I will roughly follow notes by J. Weinstein, and for the latter part notes taken by T. Feng during a course given by Z. Yun.
