Graded decomposition numbers for cyclotomic Hecke algebras

Representation Theory 2009-10-26 v3

Abstract

In recent joint work with Wang, we have constructed graded Specht modules for cyclotomic Hecke algebras. In this article, we prove a graded version of the Lascoux-Leclerc-Thibon conjecture, describing the decomposition numbers of graded Specht modules over a field of characteristic zero.
