Abstract
For a generalized triangular matrix ring $T=\left[\begin{array}{cc}R & M \\0 & S\end{array} \right]$,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 arecompositions of an inner homomorphism and an extended or a twisted homomorphism.
