Abstract

Let RR be a ring with identity, M,NM,N right modules over RR. An additive mapping δ\delta from RR to RR is called derivation on ring RR if it satisfies the Leibniz condition. If δ\delta is a derivation on RR and f:MNf:M \rightarrow N is a module homomorphism over RR, then an additive mapping d:MNd:M \rightarrow N is called a (δ,f)(\delta,f)-derivation if it satisfies d(xa)=d(x)a+f(x)δ(a)d(xa)=d(x)a+f(x)\delta(a) for all xMx \in M and aRa \in R. An additive mapping δ:RR\delta: R \rightarrow R is called Jordan derivation on ring RR if δ(x2)=δ(x)x+xδ(x)\delta(x^2)=\delta(x)x+x\delta(x) for all xRx \in R, which is the generalization of derivation This paper presents generalization of Posner's First Theorem of (δ,f)(\delta,f)-derivation on 22-torsion prime modules. It also provides a generalization of some results in case of 22-torsion free prime modules from ring situation. Moreover, we introduce a Jordan (δ,f)(\delta,f)-derivation on modules and prove that every Jordan (δ,f)(\delta,f)-derivation on modules is a (δ,f)(\delta,f)-derivation on modules.
