Course Overview

This course is a survey of the theory of Shimura varieties. It is a sequel to my Fall 2011 course on automorphic forms, although that won't be a prerequisite.

In the setting of the Langlands program, Shimura varieties provide a crucial link between automorphic forms and Galois representations. We'll begin by studying the process by which a two-dimensional Galois representation is attached to a cuspidal Hecke eigenform. Then we will work through Deligne's proof of the Ramanujan conjecture for cusp forms via the Weil conjectures. Further topics may include: Abelian varieties, Shimura curves, Deligne's formalism of Shimura varieties for general groups, and the association of Galois representations to higher-rank automorphic forms.


Algebraic number theory (number fields, local fields, Galois theory) and some algebraic geometry.


Weekly assignments account for 100% of your grade in this course. Assignments will appear on this page. These are to be turned in to me during lecture, or in my mailbox, or e-mailed to me as a PDF. Working together is encouraged, but everything you turn in must be in your own words.

Assignment 1, due Sept. 12.

Assignment 2, due Sept. 24.

Assignment 3, due Oct. 17.
