The 2-adic valuations of differences of Stirling numbers of the second kind

Wei Zhao, Jianrong Zhao, Shaofang Hong

Let $m, n, k$ and $c$ be positive integers. Let $ν_{2} (k)$ be the 2-adic valuation of $k$ . By $S (n, k)$ we denote the Stirling numbers of the second kind. In this paper, we first esta…

Asymptotic behavior of the least common multiple of consecutive arithmetic progression terms

Guoyou Qian, Shaofang Hong

Let $l$ and $m$ be two integers with $l > m \geq 0$ , and let $a$ and $b$ be integers with $a \geq 1$ and $a + b \geq 1$ . In this paper, we prove that $\log {\rm lcm}_{mn<i\le ln}\{ai+b\} =An…

Renormalization of multiple zeta values

Li Guo, Bin Zhang

Multiple zeta values (MZVs) in the usual sense are the special values of multiple variable zeta functions at positive integers. Their extensive studies are important in both mathem…
