A module M is called t-quasi-continuous if M is t-extending and whenever A and B are nonsingular direct summands of M with A∩B=0, then A⊕B is a direct summand of M. The class of t-quasi-continuous ...

An interesting result, obtaining by some theorems of Asano, Kothe and Warfield, states that: “for a commutative ring R, every module is a direct sum of uniform modules if and only if R is an Artinian principal ideal ring.” Moreover, it is observe

We introduce and investigate t-continuous modules. A module M is called t-continuous if M is t-extending, and every submodule of M which contains Z2(M) and is isomorphic to a direct summand of M, is itself a direct summand. The t-continuous property

We determine rings R with the property that all (finitely generated) nonsingular right R-modules have projective covers. These are just the rings with t-supplemented (finitely generated) free right modules. Hence, they are called right (finitely) Σ-

We introduce the notion of t-Rickart modules as a generalization of t-Baer modules. Dual t-Rickart modules are also defined. Both of these are generalizations of continuous modules. Every direct summand of a t-Rickart (resp., dual t-Rickart) module i

We study the rings R for which every R-module is almost injective. For such a ring R, it is shown that R/Soc(RR) is semisimple and Rad(R) is finitely generated. It is proved that these rings are exactly Artinian serial rings with Rad(R)2 = 0, if one

We define and investigate t-semisimple modules as a generalization of semisimple modules. A module M is called t-semisimple if every submodule N contains a direct summand K of M such that K is t-essential in N. T-semisimple modules are Morita invaria

We introduce the notions of “t-extending modules,” and “t-Baer modules,” which are generalizations of extending modules. The second notion is also a generalization of nonsingular Baer modules. We show that a homomorphic image (hence a direct
