关于Calogero-Moser系统的几何

On the geometry of the Calogero-Moser system

Wim Couwenberg, Gert Heckman, Eduard Looijenga

摘要:

本文讨论了与根系相关联的量子化周期Calogero-Moser系统的一种特殊本征态。这种状态具有这样的性质:当其本征函数作为相应的半单复李群的正则共轭类空间上的多值函数时,根据仿射Hecke代数的复反射表示,其本征函数在单值下变换,从而使共轭类空间具有射影结构.在一定的参数范围内,这种射影结构是复双曲结构的基础。如果另外满足Schwarz型的完整性条件,则它甚至具有球商减去Heegner因子的结构。例如,具有三折单值表示的根系E_8的情况描述了在特定约束下射影直线上12个无序点的系统的特殊本征态。

英文摘要:

We discuss a special eigenstate of the quantized periodic Calogero-Moser system associated to a root system. This state has the property that its eigenfunctions, when regarded as multivalued functions on the space of regular conjugacy classes in the corresponding semisimple complex Lie group, transform under monodromy according to the complex reflection representation of the affine Hecke algebra.We show that this endows the space of conjugacy classes in question with a projective structure. For a certain parameter range this projective structure underlies a complex hyperbolic structure. If in addition a Schwarz type of integrality condition is satisfied, then it even has the structure of a ball quotient minus a Heegner divisor. For example, the case of the root system E_8 with the triflection monodromy representation describes a special eigenstate for the system of 12 unordered points on the projective line under a particular constraint.
