    The workshop will have several goals, including: describing the latest results on the cohomology of Shimura varieties;explaining the key ideas and techniques which underly these results; analyzing the applications of these results to the construction of Galois representations attached to automorphic forms, with the goal of describing the state of the art in this problem. Following an old suggestion of Clozel, recently realized by Harris-Lan-Taylor-Thorne for characteristic $0$ cohomology classes, one realizes the cohomology of the locally symmetric spaces for $\mathrm{GL}_n$ as a boundary contribution of the cohomology of symplectic or unitary Shimura varieties, so that the key problem is to understand torsion Cited by:

A mixed Shimura variety is pure when the associated algebraic group is reductive. The treatment of chapter 1 follows [D2] x1. The next problem we have to deal with is how to make mixed Shimura varieties al-gebraic. AN EXAMPLE-BASED INTRODUCTION TO SHIMURA VARIETIES 3 References 65 Index 72 1. Introduction Shimura varieties are generalizations of modular curves, which have played an important role in many recent developments of number theory.

Torsion in the Coherent Cohomology of Shimura Varieties and Galois Representations Abstract We introduce a method for producing congruences between Hecke eigenclasses, possibly torsion, in the coherent cohomology of automorphic vector bundles on certain good reduction Shimura varieties. tute Summer School entitled “Harmonic Analysis, the Trace Formula, and Shimura Varieties.” It was held at the Fields Institute in Toronto, Canada, from June 2 to J The main goal of the School was to introduce graduate students and young mathematicians to three broad and interrelated areas in the theory of automorphic forms.

Both methods first realize the Hecke eigenvalues of interest in the cohomology with compact support of the open Shimura variety by an analysis of the boundary and then show that they also occur in some space of p-adic cusp forms.
