Weak injective covers and dimension of modules
Z Gao, Z Huang - Acta Mathematica Hungarica, 2015 - Springer
For a ring R, we prove that all left R-modules have weak injective covers and weak injective
preenvelopes. Then we characterize the right weak injective dimension of modules in terms …

Some examples in Gorenstein multiplicative ideal theory
S Xing - Communications in Algebra, 2022 - Taylor & Francis
In this paper, we construct some non-integrally closed domains in Gorenstein multiplicative
ideal theory. For example, we show that there exists a Gorenstein Prüfer domain which is …

Gorenstein objects in the category of -complexes
B Lu - Journal of Algebra and Its Applications, 2021 - World Scientific
For an integer N≥ 2 and three subcategories 𝒲, 𝒳, 𝒴 of modules, we study the notion of (𝒲,
𝒳, 𝒴)-Gorenstein N-complexes. We show that under certain hypotheses, an N-complex C is …
