Cotorsion modules relative to a hereditary torsion theory
Lei Qiao
This paper investigates various classes of cotorsion modules relative to the hereditary torsion theory induced by the so-called -operation. To achieve this, we first intro…
A new version of a theorem of Kaplansky
Fanggui Wang, Lei Qiao
A well-known theorem of Kaplansky states that any projective module is a direct sum of countably generated modules. In this paper, we prove the -version of this theorem, where $…
On -Injective Modules and -Injective Dimensions
Tao Xiong, Fanggui Wang, Lei Qiao +2
Let be a ring, and a fixed nonnegative integer. An -module is called -injective if for any -module with flat dimension at mo…
Super finitely presented modules and Gorenstein projective modules
Fanggui Wang, Lei Qiao, Hwankoo Kim
Let be a commutative ring. An -module is said to be super finitely presented if there is an exact sequence of -modules $\cdots\rightarrow P_n\rightarrow\cdots \righta…
