On splitting in hereditary torsion theories

R Bernhardt - Pacific Journal of Mathematics, 1971 - msp.org
Let (𝒯, ℱ) denote a hereditary torsion theory for the category of modules over a ring R. In this
paper the splitting of projective modules is studied, and it is shown that this is not equivalent …

Relative cohomology of complexes based on cotorsion pairs

L Zhongkui, X Zongyang - Journal of Algebra and Its Applications, 2020 - World Scientific
Let R be an associative ring with identity. The purpose of this paper is to establish relative
cohomology theories based on cotorsion pairs in the setting of unbounded complexes of …

Relative FI-injective and FI-flat modules

L Duan, B Ouyang - Indian Journal of Pure and Applied Mathematics, 2011 - Springer
Let R be a ring, na fixed nonnegative integer and FP n (F n) the class of all left (right) R-
modules of FP-injective (flat) dimensions at most n. A left R-module M (resp., right R-module …

Decomposition of injective modules relative to a torsion theory

JL Bueso, P Jara, B Torrecillas - Israel Journal of Mathematics, 1985 - Springer
If R is a right noetherian ring, the decomposition of an injective module, as a direct sum of
uniform submodules, is well known. Also, this property characterises this kind of ring. ML …

Divisible modules with respect to a torsion theory

I CRIVEI, S CRIVEI - Algebras, Rings And Their Representations, 2006 - World Scientific
For a hereditary torsion theory τ, a module is called τ-divisible if it is injective with respect to
every monomorphism having a τ-torsionfree cokernel. Alongside of some properties of the …

[HTML][HTML] Minimal semi-flat-cotorsion replacements and cosupport

T Nakamura, P Thompson - Journal of Algebra, 2020 - Elsevier
Over a commutative noetherian ring R of finite Krull dimension, we show that every complex
of flat cotorsion R-modules decomposes as a direct sum of a minimal complex and a …
