geometry and division algebras

abstract:

in this talk i will introduce the study of finite dimensional division algebras and the brauer group, and i will discuss the fundamental problem of computing the index of a brauer class. it turns out that algebraic geometry can play an important role in this problem. in particular i will describe the theory of twisted sheaves and how it allows one to solve this problem in certain cases.
