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 (Note: The preprint has been revised substantially, and as a result some of the information in the slides is now outdated.)
