| Abstract: | In this paper, we introduce the class of generalized stable rings and investigate equivalent characterizations of such rings. We show that EndR R is a generalized stable ring if and only if any right H-module decompositions M = A 1 + B 1 = A 2 + B 2 with A 1 ? A ? A 2 implies that there exist C,D,E ≤ M such that M = C + D B 1 = c + E + B 2 with.C ? A. Also we show that every generalized stable ring is a GE-ring and matrices over generalized stable regular ring can be diagonalized by some weakly invertible matrices. |
