Abstract

Let R be a ring and M be an R-bimodule. A mapping d:R→M (not necessarily additive) is called multiplicative derivation of R if d(xy)=d(x)y+xd(y) for all x,y∈R. In this paper, we intend to establish the additivity of d under some suitable restrictions. Moreover, we introduce multiplicative semi-derivations of rings and discuss their additivity.
