Abstract

Let $R$ be a prime ring and $I$ a nonzero ideal of $R$. Let $\a,\, \n,\, \t: R \to R$ be the endomorphisms and $\b,\, \m: R \to R$ the automorphisms. If $R$ admits a generalized $(\a, \b)$-derivation $g$ associated with a nonzero $(\a, \b)$-derivation $\d$ such that $g([\m(x), y])=[\nu(x), y]_{\a, \t}$ for all $x, y \in I$, then $R$ is commutative.
