量子仿射Knizhnik-Zamolodchikov方程和量子球函数,I

Quantum affine Knizhnik-Zamolodchikov equations and quantum spherical functions, I

Jasper V. Stokman

摘要:

Cherednik量子仿射Knizhnik-Zamolodchikov方程与仿射Hecke代数模M相关联,构成复环面T上作用于M值函数的q-差分方程的完整系统。本文将量子仿射Knizhnik-Zamolodchikov方程与Cherednik-Macdonald理论联系起来,当M是由仿射Hecke代数的标准抛物子代数的特征标导出时.我们建立了量子仿射KZ方程的解之间的对应关系,一方面,解决了Cherednik-Dunkl q-差分反射算子的谱问题(Kasatani和Takeyama的推广工作),另一方面,解决了Cherednik-Macdonald q-差分算子的谱问题(Cherednik的推广工作)。对应关系适用于T上所有相关函数空间和所有参数值,包括q和/或Hecke代数参数是单位根的情况。

英文摘要:

Cherednik's quantum affine Knizhnik-Zamolodchikov equations associated to an affine Hecke algebra module M form a holonomic system of q-difference equations acting on M-valued functions on a complex torus T. In this paper the quantum affine Knizhnik-Zamolodchikov equations are related to the Cherednik-Macdonald theory when M is induced from a character of a standard parabolic subalgebra of the affine Hecke algebra. We set up correspondences between solutions of the quantum affine KZ equations and, on the one hand, solutions to the spectral problem of the Cherednik-Dunkl q-difference reflection operators (generalizing work of Kasatani and Takeyama) and, on the other hand, solutions to the spectral problem of the Cherednik-Macdonald q-difference operators (generalizing work of Cherednik). The correspondences are applicable to all relevant spaces of functions on T and for all parameter values, including the cases that q and/or the Hecke algebra parameters are roots of unity.
