Blocks of Ariki-Koike algebras and level-rank duality

Abstract

We study the blocks for Ariki-Koike algebras using a general notion of core for ll-partitions. We interpret the action of the affine symmetric group on the blocks in the context of level rank duality and study the orbits under this action.
