Abstract

For a generalized triangular matrix ring $T=\[\array{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 ${\alpha}$ 's and all ${\alpha}$ -derivations of T. Some of the homomorphisms are compositions of an inner homomorphism and an extended or a twisted homomorphism.

Keywords
