On the representation dimension of skew group algebras, wreath products and blocks of Hecke algebras

Published 29 Apr 2012 in math.RT and math.RA | (1204.6510v1)

Abstract: We establish bounds for the representation dimension of skew group algebras and wreath products. Using this, we obtain bounds for the representation dimension of a block of a Hecke algebra of type A, in terms of the weight of the block. This includes certain blocks of group algebras of symmetric groups.
