NOTES ON GENERALIZED DERIVATIONS OF *-PRIME RINGS
(UNIV MISKOLC INST MATH, 2014)
Let R be a *-prime ring with characteristic different from two and U not equal 0 be a square closed *-Lie ideal of R. An additive mapping F : R -> R is called an generalized derivation if there exits a derivation d : R -> ...
A NOTE ON (sigma,tau)-DERIVATIONS OF RINGS WITH INVOLUTION
(UNIV MISKOLC INST MATH, 2014)
Let R be a 2-torsion free simple *-ring and D: W R -> R be an additive mapping satisfiying D(xx) = D(x)sigma(x*) +tau(x)D(X*) for all x epsilon R: Then D is (sigma,tau)-derivation of R or R is S-4 ring. Also, if R is a ...
