摘要:The center Zn(q) of the integral group algebra of the general linear group GLn(q) over a finite field admits a filtration with respect to the reflection length. We show that the structure constants of the associated graded algebras GLn(q) are independent of n, and this stability leads to a universal stable center with positive integer structure constants which governs the algebras GLn(q) for all n. Various structure constants of the stable center are computed and several conjectures are formulated. This generalizes the stability properties for symmetric groups and wreath products were established earlier in literature. This is based on a joint work with Weiqiang Wang.
