W-graph ideals

Robert B. Howlett, Van M. Nguyen

Published 2010-12-06, updated 2011-08-24Version 2

We introduce a concept of a W-graph ideal in a Coxeter group. The main goal of this paper is to describe how to construct a W-graph from a given W-graph ideal. The principal application of this idea is in type A, where it provides an algorithm for the construction of W-graphs for Specht modules.
