伪因子、椭圆函数和连分数
Pseudo-factorials, elliptic functions, and continued fractions
摘要:
伪因子的递归关系是通常因子的递归关系的扭曲形式。这些数字与特殊的椭圆函数,最值得注意的是,一个迪克森和维尔斯特拉斯函数,参数化的费马三次曲线和相对于一个六边形晶格。本文建立了首次在经验上发现的伪因子的普通母函数的连分数展开式。本文还提供了相关的正交多项式,这似乎形成一个新的家庭的“椭圆多项式”,以及各种其他性质的伪Face,包括一个六角格和表达式和基本同余的特征。
英文摘要:
This study presents miscellaneous properties of pseudo-factorials, which are numbers whose recurrence relation is a twisted form of that of usual factorials. These numbers are associated with special elliptic functions, most notably, a Dixonian and a Weierstrass function, which parametrize the Fermat cubic curve and are relative to a hexagonal lattice. A continued fraction expansion of the ordinary generating function of pseudo-factorials, first discovered empirically, is established here. This article also provides a characterization of the associated orthogonal polynomials, which appear to form a new family of "elliptic polynomials", as well as various other properties of pseudo-factorials, including a hexagonal lattice sum expression and elementary congruences.
