Mittag-Leffler conditions on modules
We study Mittag-Leffler conditions on modules providing relative versions of classical results
by Raynaud and Gruson. We then apply our investigations to several contexts. First of all, we …

A test for finite representation type
I Herzog - Journal of Pure and Applied Algebra, 1994 - Elsevier
Let R be a left pure-semisimple ring. It is proved that if R has self-duality or if R is a
polynomial identity ring, then R is of finite representation type. If there exists an example of a …

Endofinite modules and pure semisimple rings
NV Dung, JL García - Journal of Algebra, 2005 - Elsevier
Let R be a right pure semisimple ring, ie, a ring R such that every right R-module is a direct
