CalTitle1: The categorifed braid group action and its consequences

Auth: kevinc@pkevinc.pc (assumed)

Peter McNamara (University of Queensland) Friday 22 April, 12-1pm, Place: Carslaw 375 The categorifed braid group action and its consequences It is well known that the braid group acts on a quantised enveloping algebra by algebra automorphisms. We discuss the categorification of this braid group action and some of its consequences. Applications include constructing reflection functors for KLR algebras, and a theory of restricting a categorical representation along a face of a Weyl polytope.
