广义余割数与Hurwitz Zeta函数

Generalized Cosecant Numbers and the Hurwitz Zeta Function

Victor Kowalenko

摘要:

本文总结了关于广义余割数$c_{ρ,k}$的最新进展,它代表了重要的基本函数$z^ρ/\sin^ρ z$的幂级数展开式的系数。这些系数是通过幂级数展开的分区方法获得的,包括$ρ$的复数值,该方法比标准泰勒级数方法更通用,但当两者都可以应用时,产生与后者相同的结果,尽管形式不同。令人惊讶的是,广义余割数是次数为$k$的$ρ$中的多项式,其中$k$是$z$的幂。给出了广义余割数中最高阶项系数的一般公式。然后,它示出了如何广义余割数与特定的对称多项式从求和整数的二次幂。因此,赫尔维茨zeta函数的整数值为偶数的权力,有史以来第一次表示的广义余割数的比率。

英文摘要:

This announcement paper summarises recent development concerning the generalized cosecant numbers $c_{ρ,k}$, which represent the coefficients of the power series expansion for the important fundamental function $z^ρ/\sin^ρ z$. These coefficients are obtained for all, including complex, values of $ρ$ via the partition method for a power series expansion, which is more versatile than the standard Taylor series approach, but yields the same results as the latter when both can be applied, though in a different form. Surprisingly, the generalized cosecant numbers are polynomials in $ρ$ of degree $k$, where $k$ is the power of $z$. General formulas for the coefficients of the highest order terms in the generalized cosecant numbers are presented. It is then shown how the generalized cosecant numbers are related to the specific symmetric polynomials from summing over quadratic powers of integers. Consequently, integral values of the Hurwitz zeta function for even powers are expressed for the first time ever in terms of ratios of the generalized cosecant numbers.
