Notes on generalized Jordan ( \sigma,\tau) *-derivations of semiprime rings with involution

Résumé

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.
