| Abstract | ||
| As a complement to the former work of GZ-regular modules, in this paper along the lines of Z-regular modules due to Zelmanowitz, we improve the study of the endomorphism ring of Z-regular modules to GZ-regular modules. We give a sufficient condition on GZ-regular module M such that S=End(M) is π-regular ring and we prove that R-module M is GZ-regular if and only if S=End(M) is π-regular ring in case that M is a projective finitely power generated R-module. Also we show that for a GZ-regular R-module M, the center of S=End(M), Cen(S), is π-regular ring. Even further if M is a GZ-regular R-module then R/ann(M) is dense in Cen(S). | ||
