Hello all, The next MaPSS talk of this semester will be at 17:00 on Mon 10th September in Carslaw 535. It’s a great opportunity to meet fellow postgrads, listen to an interesting talk, and of course get free food! ************************************************************************************** Speaker: Alexander Kerschl Title: Graded Cellularity and Diagrams Abstract: In 1996 Graham and Lehrer introduced the concept of cellular algebras. This structure is a powerful tool to study the representation theory of the underlying algebra. So can all the simple modules just be found as quotients of the so called cell modules. This comes, however, with the cost of us having to know the algebra well enough already to see that it is cellular. In modern representation theory we mostly work with diagram algebras though and most of them are known to be cellular. As an example we will talk about the quiver Hecke algebra of type A and the diagramatic Cherednik Algebra. The aim of the talk is not necessarily to give a complete introduction, rather we want to show that cellularity and diagrams can be used as great tools to understand problems and do computations with them. ************************************************************************************** See you there!
