超几何函数的单值投影PSL(2,F7)的达布估计
Darboux evaluations for hypergeometric functions with the projective monodromy PSL(2,F7)
摘要:
代数超几何函数在单值群较简单的情况下,如有限的循环群,可以紧表示为拉回曲线上的根函数。这些所谓的达布评价已经考虑了代数2F 1-函数。本文给出了3F 2-函数在单值投射群PSL(2,F7)上的经典情形的Darboux估计.作为应用,得到了相同3F 2-函数的模求值。
英文摘要:
Algebraic hypergeometric functions can be compactly expressed as radical functions on pull-back curves where the monodromy group is simpler, say, a finite cyclic group. These so-called Darboux evaluations were already considered for algebraic 2F1-functions. This article presents Darboux evaluations for the classical case of 3F2-functions with the projective monodromy group PSL(2,F7). As an application, appealing modular evaluations of the same 3F2-functions are derived.
