Notes on Generalized Jordan ( \sigma,\tau) *-Derivations Of Semiprime Rings With Involution

Abstract

Let R be a 6-torsion free semiprime *-ring, \\tau an endomorphism of R, \\sigam an epimorphism of R and f : R ! R an additive mapping. In this paper we proved the following result: f is a generalized Jordan ( \\sigma,\\tau) *-¡derivation if and only if f is a generalized Jordan triple ( \\sigma,\\tau) *-derivation.
