Algebra Seminar: McNamara -- The categorifed braid group action and its consequences

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.
