Abstract

For a generalized triangular matrix ring T = R M 0 S , over rings R and S having only the idempotents 0 and 1 and over an (R;S)-bimodule M, we characterize all homomorphisms 's and all - derivations of T. Some of the homomorphisms are compositions of an inner homomorphism and an extended or a twisted homomorphism.
