DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ENAAS/74/">C
 orestriction</a>\nby Erhard Neher (University of Ottawa) as part of Europe
 an Non-Associative Algebra Seminar\n\n\nAbstract\nCorestriction is an impo
 rtant technique in the theory of central-simple associative algebras over 
 a field. Given a finite étale extension K/F\, e.g. a Galois extension\, c
 orestriction associates a central-simple associative F-algebra with every 
 central-simple associative K-algebra. In this talk\, I will give an introd
 uction to corestriction over fields\, applicable to nonassociative algebra
 s. Towards the end of my talk\, I will indicate why it is of interest to g
 eneralize corestruction to  schemes and sketch how this can be done (joint
  work Philippe Gille and Cameron Ruether).\n
