Seminar: What is ... Descent Theory for Hopf Algebras?

Clarisson Canlubo will talk about: What is Descent Theory for Hopf Algebras?

Descent theory concerns itsself with finding out when and how one can deduce that a mathematical structure on a mathematical object X  has "descended" from another mathematical object Y covering X in some way. In this seminar Clarisson Canlubo will explain the version of this problem that arises in the theory of Hopf algebras.

This lecture is part of the "What is...?" seminar.
