A note on (?, ?)-derivations of rings with involution
Koç E.; Gölbaşi O. (2014)Let R be a 2-torsion free simple *-ring and D : R ? R be an additive mapping satisfiying D(xx*)= D(x)?(x*)+?(x)D(x*), for all x ? R. Then D is a (?, ?)-derivation of R or R is S4 ring. Also, if R is a 2-torsion free semiprime ... -
Notes on generalized (?, ?)-derivation
Gölbaşi O.; Koç E. (2010)Let R be a prime ring with charR ? 2 and let ?, ? be automorphisms of R. An additive mapping f: R ? R is called a generalized (?, ?)-derivation if there exists a (?, ?)-derivation d: R ? R such that f(xy) = f(x)?(y) + ... -
