WDVV方程和广义Calogero-Moser-Sutherland方程组的三角解

Trigonometric Solutions of WDVV Equations and Generalized Calogero-Moser-Sutherland Systems

Misha V. Feigin

摘要:

我们考虑WDVV方程的三角解,并导出几何条件时,一组向量的多重性确定这样的解决方案。我们将这些条件纳入三角Veselov系统($\vee$ -系统)的概念,我们确定所有三角$\vee$ -系统多达五个向量。我们证明了广义Calogero-Moser-Sutherland算子存在一个分解的本征函数当且仅当它对应于三角$\vee$ -系统;这颠倒了Veselov对有理解观察到的单向蕴涵。

英文摘要:

We consider trigonometric solutions of WDVV equations and derive geometric conditions when a collection of vectors with multiplicities determines such a solution. We incorporate these conditions into the notion of trigonometric Veselov system ($\vee$-system) and we determine all trigonometric $\vee$-systems with up to five vectors. We show that generalized Calogero-Moser-Sutherland operator admits a factorized eigenfunction if and only if it corresponds to the trigonometric $\vee$-system; this inverts a one-way implication observed by Veselov for the rational solutions.
