Abstract
Let R be a ring. A map \({F : R \rightarrow R}\) is called a multiplicative (generalized)-derivation if F(xy) = F(x)y + xg(y) is fulfilled for all \({x, y \in R}\) where \({g : R \rightarrow R}\) is any map (not necessarily derivation). The main objective of the present paper is to study the following situations: (i) \({F(xy) \pm xy \in Z}\), (ii) \({F(xy) \pm yx \in Z}\), (iii) \({F(x)F(y) \pm xy \in Z}\) and (iv) \({F(x)F(y) \pm yx \in Z}\) for all x, y in some appropriate subset of R. Moreover, some examples are also given.
