Heun超几何函数与Gauss超几何函数之间的参数变换

Parametric transformations between the Heun and Gauss hypergeometric functions

Raimundas Vidunas, Galina Filipuk

摘要:

超几何函数和Heun函数是经典的特殊函数。它们之间的变换公式通常由它们的微分方程关于某些覆盖P1-to-P1的拉回变换导出。这给出了Heun函数的表达式,用更好理解的超几何函数表示。本文给出了具有自由连续参数的超几何到Heun拉回变换的列表,并通过Heun到超几何的约化公式说明了其中的大多数。总共有61个参数变换,最大度为12。

英文摘要:

The hypergeometric and Heun functions are classical special functions. Transformation formulas between them are commonly induced by pull-back transformations of their differential equations, with respect to some coverings P1-to-P1. This gives expressions of Heun functions in terms of better understood hypergeometric functions. This article presents the list of hypergeometric-to-Heun pull-back transformations with a free continuous parameter, and illustrates most of them by a Heun-to-hypergeometric reduction formula. In total, 61 parametric transformations exist, of maximal degree 12.
