Multiplicative derivations on rank- $s$ matrices for relatively small $s$

Xiaowei Xu, Baochuan Xie, Yanhua Wang +1

Let $n$ and $s$ be fixed integers such that $n \geq 2$ and $1 \leq s \leq \frac{n}{2}$ . Let $M_{n} (K)$ be the ring of all $n \times n$ matrices over a field $K$ . If a m…

$X$ -Gorenstein projective dimensions

Zhibing Zhao, Xiaowei Xu

In this paper, we mainly investigate the $X$ -Gorenstein projective dimension of modules and the (left) $X$ -Gorenstein global dimension of rings. Some properti…

Left Derivations and Strong Commutativity Preserving Maps on Semiprime $Γ$ -Rings

Xiaowei Xu, Jing Ma, Yuan Zhou

In this paper, firstly as a short note, we prove that a left derivation of a semiprime $Γ$ -ring $M$ must map $M$ into its center, which improves a result by Paul and Halder and som…

Skew $N$ -Derivations on Semiprime Rings

Xiaowei Xu, Yang Liu, Wei Zhang

For a ring $R$ with an automorphism $σ$ , an $n$ -additive mapping $Δ : R \times R \times ... \times R \to R$ is called a skew $n$ -derivation with respect to $σ$ if it is always a…
