Talk given at Representations of Algebraic Groups and Related Objects (AlgDar2014) in Jena, Germany on 8 September 2014. Here are the slides for the talk. This is based on joint work with Dave Benson.
Decomposing tensor products of irreducible representations of algebraic groups in positive characteristic
Given at the conference Cohomology in Lie Theory, University of Oxford, 24-28 June 2013. This talk is about an elementary approach to generalized q-Schur algebras via a simple defining presentation by generators and relations. It is mostly based on the preprint arXiv: 1012.5983. Here are the slides for the talk and here is a printable version of the slides. (Note: The preprint has been revised substantially, and as a result some of the information in the slides is now outdated.)
Talk at the Boulder AMS meeting, 13th April 2013. Here are the slides for the talk. This is based on joint work with Richard Dipper and Friederike Stoll.
