Notes On Generalized (sigma, tau)-Derivation
Abstract
Let R be a prime ring with charR not equal 2 and let sigma, tau be automorphisms of R. An additive mapping f : R -> R is called a generalized (sigma, tau)-derivation if there exists a (sigma, tau)-derivation d : R -> R such that f(xy) = f(x)sigma(y)+tau(x)d(y) holds for all x,y is an element of R. In this paper, some well known results concerning generalized derivations of prime rings are extended to generalized (sigma,tau)-derivations.
