Goldie rank of primitive quotients via lattice point enumeration
Joanna Meinel, Catharina Stroppel
Let k be an algebraically closed field of characteristic 0. Musson and vandenBergh classified primitive ideals for rings of torus invariant differential operators. This classificat…
Fusion rings for quantum groups
Henning Haahr Andersen, Catharina Stroppel
We study the fusion rings of tilting modules for a quantum group at a root of unity modulo the tensor ideal of negligible tilting modules. We identify them in type A with the combi…
2-row Springer fibres and Khovanov diagram algebras for type D
Michael Ehrig, Catharina Stroppel
We study in detail two row Springer fibres of even orthogonal type from an algebraic as well as topological point of view. We show that the irreducible components and their pairwis…
A graphical description of Kazhdan-Lusztig polynomials
Tobias Lejczyk, Catharina Stroppel
We give an easy diagrammatical description of the parabolic Kazhdan-Lusztig polynomials for the Weyl group of type with parabolic subgroup of type and consequentl…
