摘要:

紧致黎曼曲面和它们的阿贝尔函数是求解可积方程的工具;最近Monster的表示论和相关的模形式指出了$τ$ -函数的相关性,而这些函数又与一种特定类型的阿贝尔函数,(Kleinian)$σ$ -函数相关联。本文利用黎曼曲面上一点上Weierstrass半群的性质,构造了$σ$ -函数,作为黎曼曲面平面仿射模型构造的推广.因为我们的定义是代数的,我们能够考虑的性质的$σ$ -功能,包括其雅可比反演公式,并给予观察其性质的诺顿基础上的可复制的功能,反过来有关的蒙托月光。

英文摘要:

Compact Riemann surfaces and their abelian functions are instrumental to solve integrable equations; more recently the representation theory of the Monster and related modular form have pointed to the relevance of $τ$-functions, which are in turn connected with a specific type of abelian function, the (Kleinian) $σ$-function. This paper proposes a construction of $σ$-functions based on the nature of the Weierstrass semigroup at one point of the Riemann surface as a generalization of the construction of plane affine models of the Riemann surface. Because our definition is algebraic, we are able to consider the properties of the $σ$-functions including their Jacobi inversion formulae, and to give an observation of their properties to those of a Norton basis for replicable functions, in turn relevant to the Monstrous Moonshine.
