On Hollow-Lifting Modules
(Mathematical Soc Rep China, 2007)
Let R be any ring and let M be any right R-module. M is called hollow-lifting if every submodule N of M such that M/N is hollow has a coessential submodule that is a direct summand of M. We prove that every amply supplemented ...
On T-Noncosingular Modules
(Cambridge Univ Press, 2009)
In this paper we introduce T-noncosingular modules. Rings for which all right modules are T-noncosingular are shown to be precisely those for which every simple right module is injective. Moreover, for any ring R we show ...
