Kazhdan constants of some colored permutation groups

[摘要] Colored permutation groups serve as a generalization of Coxeter groups of types A and B. We compute exact Kazhdan constants for the Coxeter groups of types B and D, and for colored permutation groups. The computations rely on the combinatorics of Young tableaux and on suitable decompositions of representation spaces. (C) 2004 Elsevier Inc. All rights reserved.
