Kazhdan–Lusztig Cells in Affine Weyl Groups of Rank 2

Jérémie Guilhot (East Anglia), 17th December 2009

Abstract

In this talk after introducing the concept of Kazhdan–Lusztig cells, I will show how one can determine the partition of an affine Weyl group of rank 2 into cells for all parameters from the knowledge of cells in all proper (hence finite) parabolic subgroups.
