On Rad-D-12 Modules
(Ovidius Univ Press, 2013)
Let M be a right R-module. We call M Rad-D-12, if for every submodule N of M, there exist a direct summand K of M and an epimorphism alpha : K -> M/N such that Ker alpha subset of Rad(K). We show that a direct summand of ...
Rings Whose Pure-Injective Right Modules Are Direct Sums of Lifting Modules
(Academic Press Inc Elsevier Science, 2013)
It is shown that every pure-injective right module over a ring R is a direct sum of lifting modules if and only if R is a ring of finite representation type and right local type. In particular, we deduce that every left ...
On (D-12)-Modules
(Rocky Mt Math Consortium, 2013)
is known that a direct summand of a (D-12)module need not be a (D-12)-module. In this paper we establish some properties of completely (D-12)-modules (modules for which every direct summand is a (D-12)-module). After giving ...
