Distributive Laws and Noncommutative Fibrations
Atabey Kaygun
Istanbul Technical University, Turkey
Özet : In noncommutative geometry there is a good working definition of a principal fibration whose structure group is no longer a group but a Hopf algebra, and there are few competing definitions for a generic fiber bundle. In this talk I am going to investigate one possible definition for noncommutative fibrations with examples coming from combinatorics: unramified coverings of connected graphs. Time permiting, I am also going to investigate the homological properties of such fibrations.
