复反射群的格林函数II
Green functions associated to complex reflection groups, II
摘要:
在我们以前的文章中,讨论了复反射群G(e,1,n)的格林函数。它涉及B_n或C_n型典型群的格林函数的组合方法。本文引入了复反射群G(e,p,n)的格林函数。我们定义了与G(e,p,n)相关的Schur函数和Hall-Littlewood函数,并证明了我们的格林函数是作为这两类对称函数之间的一个转移阵而得到的.作为特例,给出了D_n型格林函数的组合处理。
英文摘要:
In our previous paper, Green functions associated to complex reflection groups G(e,1,n) were discussed. It involved a combinatorial approach to the Green functions of classical groups of type B_n or C_n. In this paper, we introduce Green functions associated to complex reflection groups G(e,p,n). We define Schur functions, Hall-Littlewood functions associated to G(e,p,n), and show that our Green functions are obtained as a transition matrix between those two kinds of symmetric functions. As a special case, it gives a combinatorial treatmnet of Green functions of type D_n.
