Decomposition Numbers for Exceptional Types

Part of the Algebra and Applications book series (AA, volume 15)


This last chapter contains explicit results concerning Iwahori-Hecke algebras of exceptional types. We present in particular the decomposition matrices for these types in characteristic 0. We also explain some basic algorithmic methods, including Parker’s MEATAXE.
