组合同余与Stirling数

Combinatorial congruences and Stirling numbers

Zhi-Wei Sun

摘要:

本文得到了一些复杂的含二项式系数的组合同余式,并证实了作者和Davis的两个结论。它们与我们对序列$\sum_{j=0}^l{l\choose j}S(j,m)a^{l-j}(l=m,m+1,...)$模素数$p$的周期性的研究密切相关,其中$a$和$m>0$是整数,并且这些$S(j,m)$是第二类斯特林数。我们还证明了$(p-1)p^{[\log_p m]}$是序列$\sum_{j=r(mod p-1)}{l\choose j}S(j,m)(l=m,m+1,...)$模$p$的一个周期,从而给出了Glasgow同余的一个新的推广.

英文摘要:

In this paper we obtain some sophisticated combinatorial congruences involving binomial coefficients and confirm two conjectures of the author and Davis. They are closely related to our investigation of the periodicity of the sequence $\sum_{j=0}^l{l\choose j}S(j,m)a^{l-j}(l=m,m+1,...)$ modulo a prime $p$, where $a$ and $m>0$ are integers, and those $S(j,m)$ are Stirling numbers of the second kind. We also give a new extension of Glaisher's congruence by showing that $(p-1)p^{[\log_p m]}$ is a period of the sequence $\sum_{j=r(mod p-1)}{l\choose j}S(j,m)(l=m,m+1,...)$ modulo $p$.
