AI总结:

本文研究了在Schottky统一化和Jacobi参数化之间翻译辅助对称性,以实现函数关系的双向转换,从而提升特殊函数的数值计算效率。

摘要:

对不同亏格的Riemann面上的函数的显式描述和计算取决于所选语言:虽然Jacobi参数化广为人知且被使用,但Schottky统一化已被证明提供了一种替代方法,特别是在(但不局限于)数值计算中很有用。尽管能够完全捕捉Riemann面的几何结构,但两种语言却受到完全不同的辅助对称性的约束。在本文中,我们将Jacobi参数化中固有的辛变换翻译并比较到Schottky统一化中用于生成Schottky群的莫比乌斯变换的自由度。我们的结果旨在将用Schottky语言表达的函数关系转换到Jacobi语言中,并 vice versa。一个直接的应用是通过有利地调整Schottky覆盖来高效地数值评估特殊函数,在物理背景下可以更快地收敛。

英文摘要:

The explicit description and computation of functions defined on Riemann surfaces of various genera depends on the choice of language: while the Jacobi parametrization is widely known and used, the Schottky uniformization has been proven to provide an alternative approach, useful in particular for (but not limited to) numerical calculations. Despite capturing the geometry of the Riemann surface completely, the two languages are subject to rather different sets of auxiliary symmetries. In this article we translate and compare the symplectic transformations inherent in the Jacobi parametrization to the freedom in choosing Möbius transformations generating the Schottky group for the Schottky uniformization. Our results are aimed at transferring functional relations expressed in the Schottky language to the Jacobi language and vice versa. An immediate application would be the efficient numerical evaluation of special functions in a physics context by favorably tuning the Schottky cover leading to quicker convergence.
