Abstract

Let RR be an associative ring with a nonzero ideal II and a semiprime ideal TT such that TI.T\subsetneq I. Let KK be a nonempty subset of RR and d:RRd:R\to R be a derivation of RR, if [d(x),x]T[d(x),x]\in T for all xK,x\in K, then dd is said to be a TT-commuting derivation on K.K. We show that if some specific TT-valued differential identities are imposed on II, then d is TT-commuting. Moreover, we provide semiprime ideal variant of some known results on derivations.
