Lie superalgebras and categorification.

Antonio Sartori (University of York)

Wednesday 7th May, 2014 16:00-17:00 Maths 204


Intertwining operators of Lie algebra representations can be used to define link invariants, like the Jones polynomial, and their categorifications provide link homology theories. In the talk, I will approach the analogous construction in the super case: I will describe a graphical calculus for representations of the general linear Lie superalgebra and I will present a categorification using the BGG category O.
