Abstract

I'll begin this talk by describing some famous finiteness theorems and conjectures. These were motivated in part trying to carry out certain kinds of calculations, e.g. by trying to describe explicitly all the rational points on an elliptic curve. I'll then describe a new finiteness problem which arises from studying deformations of complexes of modules for Galois groups.
