Generalized Derivations on Prime Near Rings

Abstract

LetNbe a near ring. An additive mappingf:N→Nis said to be a right generalized (resp., left generalized) derivation with associated derivationdonNiff(xy)=f(x)y+xd(y)(resp.,f(xy)=d(x)y+xf(y)) for allx,y∈N. A mappingf:N→Nis said to be a generalized derivation with associated derivationdonNiffis both a right generalized and a left generalized derivation with associated derivationdonN. The purpose of the present paper is to prove some theorems in the setting of a semigroup ideal of a 3-prime near ring admitting a generalized derivation, thereby extending some known results on derivations.
