In this paper we study a condition right FGTF on a ring R, namely when all finitely generated torsionless right R-modules embed in a free module. We show that for a von Neuman regular (VNR) ring R the condition is equivalent to every matrix ring Rn is a Baer ring; and this is right-left symmetric. Furthermore, for any Utumi VNR, this can be strengthened: R is FGTF iff R is self-injective.
In this article, we study modules with the weak -extending property. We prove that if satisfies weak -extending, pseudo duo, properties and has finite uniform dimension then decomposes into a direct sum of a semisimple submodule and a submodule of finite uniform dimension. In particular, if satisfies the weak -extending, pseudo duo, properties and ascending (or descending) chain condition on essential submodules then for some semisimple submodule and Noetherian (or Artinian, respectively)...
An -module is said to be an extending module if every closed submodule of is a direct summand. In this paper we introduce and investigate the concept of a type 2 -extending module, where is a hereditary torsion theory on -. An -module is called type 2 -extending if every type 2 -closed submodule of is a direct summand of . If is the torsion theory on - corresponding to an idempotent ideal of and is a type 2 -extending -module, then the question of whether or not is...
