Actions of Hopf algebras

Description:  Group algebras and enveloping algebras of Lie algebras are examples of Hopf algebras. Automorphisms acting on rings as well as derivations acting on them are examples of Hopf algebra actions. Guided by these classical examples, we will motivate the study of Hopf algebra actions and consider in particular the question, when these actions are the only possible actions of a Hopf algebra on a certain class of rings.   Date:  2018-11-16 Start Time:   11:30 Speaker:  Christian Lomp (CMUP, Univ Porto) Institution:  CMUP, University of Porto Place:  Sala 2.5, DMat UC See more:   <Main>   <UC|UP MATH PhD Program>
