GHOSSEIRI Department of Mathematics, Kurdistan University P. O. Box 416, Sanandaj, I. R. of Iran Journal Article 2004 10 30 Let R and S be reduced rings with identities whose idempotents are central, and let M be an<br />(R, S)-bimodule such that annr (M)=0. In this paper, we determine first the structure of automorphisms of<br />the triangular ring, <br /><br /><br /><br /><br />=<br />S<br />R M<br />T<br />0<br />, and then, for all automorphisms α ,β of T we determine the structure<br />of (α,β)-derivations of T. https://ijsts.shirazu.ac.ir/article_2824_9c3c1808dd2dab02b817767301f7eb17.pdf
