This paper deals with some analytic aspects of GG system introduced by I.M. Gelfand and M.I. Graev: we compute the dimension of the solution space of GG system over the field of meromorphic functions periodic with respect to a lattice. We describe the monodromy invariant subspace of the solution space. We provide a connection formula between a pair of bases consisting of $\Gamma $-series solutions of GG system associated with a pair of regular triangulations adjacent to each other in the secondary fan.

GG系统的全球分析

本文讨论了由 IM Gelfand 和 MI Graev 介绍的 GG 系统的一些分析方面:我们计算 GG 系统在关于晶格的周期性亚纯函数域上的解空间的维数。我们描述了解空间的单调不变子空间。我们提供了一个由 GG 系统的 $\Gamma $ 系列解组成的一对基之间的连接公式,这些解与二级扇中彼此相邻的一对规则三角剖分相关联。
