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…
