Decomposition numbers for generic Iwahori-Hecke algebras of noncrystallographic type

[摘要] We compute the Phi(e)-modular decomposition matrices for the generic Iwahori-Hecke algebras of type I-2(m) for m is an element of N, m > 2, H-3, and H-4, for all e is an element of N leading to nontrivial decomposition maps. The results are obtained by a combined use of different ideas from computational representation theory and by application of the computer algebra systems GAP, CHEVIE, VectorEnumerator and MeatAxe.
