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…

Necessary conditions for reversed Dickson polynomials of the second kind to be permutational

Shaofang Hong, Xiaoer Qin

In this paper, we present several necessary conditions for the reversed Dickson polynomial $E_{n} (1, x)$ of the second kind to be a permutation of $F_{q}$ . In particular,…
