Max Planck Institute
Bonn, Germany

First talk:
Etale Maps and the Algebraic Fundamental Group

ABSTRACT: The concepts of etale maps, etale morphisms, and etale extensions of commutative rings are very interrelated and are basic in the extension of covering space theory to algebraic geometry. In the first lecture we will consider the topological fundamental group as an automorphism of a functor and in the second we will explain the concept of etale algebra extension. In the fifth and sixth lectures we will survey Grothendieck's algebraic fundamental group.
