Generalized derivations on Lie ideals in prime rings

    https://doi.org/10.1142/S1793557117500322Cited by:1 (Source: Crossref)

    Let R be a 2-torsion free prime ring, and U a square closed Lie ideal of R. Further let G, and F be generalized derivations associated with derivations g and d, respectively on R. If one of the following conditions holds: (i) G(uv)+d(u)F(v)+uvZ(R), (ii) G(uv)+d(u)F(v)+vuZ(R), (iii) G(uv)+d(u)F(v)+uvZ(R), (iv) G(vu)+F(u)F(v)+uvZ(R), (v) G(uv)+d(v)F(u)+uvZ(R), for all u,vU, then it is proved that either g=d=0 or UR.
