How to think of the good old Brauer algebra?

In this talk I will discuss how categorification methods can be used to obtain a graded version of the Brauer algebra, especially in non semi-simple cases. This will involve the category O for certain orthogonal Lie algebras and their parabolic and graded analogues. The categorifications involved in this process are a generalised version of the ones introduced by Rouquier and Khovanov-Lauda in the sense that the categorified object is not a Kac-Moody algebra or quantum group, but a so-called quantum symmetric pair. This is joint work with Catharina Stroppel.
