Speaker: Dr. Emily Norton (MPIM)
The action of the Lie superalgebra p(n) on a module tensored with d copies of the standard representation leads to the definition of what we call the signed VW-algebra, which is a kind of degenerate affine signed version of the Brauer algebra. I will discuss the ingredients needed to define this algebra -- the key was the "fake Casimir element" that we constructed during the WINART workshop in Banff in March 2016. This is joint work with Balagovic, Daugherty, Entova-Aizenbud, Halacheva, Hennig, Im, Letzter, Serganova, and Stroppel.
