More than 10 years ago, Dipper, James and Murphy developed the theory of Specht modules for Hecke algebras of type B-n More recently, using Lusztig's a-function, Geck and Rouquier showed how to obtain parametrizations of the irreducible representations of Hecke algebras (of any finite type) in terms of socalled canonical basic sets. For certain values of the parameters in type B-n combinatorial descriptions of these basic sets were found by Jacon, based on work of Ariki and Foda-Leclerc-Okado-Thibon-Weish. Here, we consider the canonical basic sets for all the remaining choices of the parameters. (c) 2006 Elsevier Inc. All rights reserved.
