变形Calogero-Moser-Sutherland系统的双谱性

Bispectrality for deformed Calogero-Moser-Sutherland systems

M. Feigin

摘要:

我们证明了与配置$A_{n,2}(m), C_n(l,m)$相关的广义Calogero-Moser-Sutherland系统的双谱对偶性。修正了Baker-Akhiezer函数的三角公理,构造了有理Macdonald型的对偶差分算子和与这两种级数相关的Baker-Akhiezer函数.

英文摘要:

We prove bispectral duality for the generalized Calogero-Moser-Sutherland systems related to configurations $A_{n,2}(m), C_n(l,m)$. The trigonometric axiomatics of Baker-Akhiezer function is modified, the dual difference operators of rational Macdonald type and the Baker-Akhiezer functions related to both series are explicitly constructed.
