退化分圆Hecke代数的中心与抛物范畴O

Centers of degenerate cyclotomic Hecke algebras and parabolic category O

Jonathan Brundan

摘要:

证明了与B_d(l)型复反射群相关联的退化分圆Hecke代数的中心由交换生成元中的对称多项式组成.退化分圆Hecke代数的块的分类是一个简单的推论。进而证明了李代数gl_n(C)的抛物范畴O的整块的中心由它的泛包络代数的中心生成.

英文摘要:

We prove that the center of each degenerate cyclotomic Hecke algebra associated to the complex reflection group of type B_d(l) consists of symmetric polynomials in its commuting generators. The classification of the blocks of the degenerate cyclotomic Hecke algebras is an easy consequence. We then deduce that the center of an integral block of parabolic category O for the Lie algebra gl_n(C) is generated by the center of its universal enveloping algebra.
