Corestriction

Abstract: Corestriction is an important technique in the theory of central-simple associative algebras over a field. Given a finite étale extension K/F, e.g. a Galois extension, corestriction associates a central-simple associative F-algebra with every central-simple associative K-algebra. In this talk, I will give an introduction to corestriction over fields, applicable to nonassociative algebras. Towards the end of my talk, I will indicate why it is of interest to generalize corestruction to schemes and sketch how this can be done (joint work Philippe Gille and Cameron Ruether).
