Abstract:
A Hopf-Galois extension of an algebra is a dual notion to a principal bundle on a space. In this talk I will give an introduction to the theory by talking about what a Hopf algebra is, and also why Galois theory is not just about field extensions. The talk will mostly be (co)commutative, for those who aren't noncommutative geometers yet.
