Heaps of modules: homological aspects
Yongduo Wang, Chenyu Wang, Jian He +1
The definitions of projective objects and Gorenstein projective objects in the category of heaps of -modules are posed, where is a truss. It is shown that a heap of -modu…
Injectivity of modules over trusses
Yongduo Wang, Shujuan Han, Dengke Jia +2
As the dual notion of projective modules over trusses, injective modules over trusses are introduced. The Schanuel Lemmas on projective and injective modules over trusses are exhib…
Wakamatsu tilting subcategories and weak support tau-tilting subcategories in recollements
Yongduo Wang, Hongyang Luo, Yu-Zhe Liu +2
In this article, we prove that if (A, B, C) is a recollement of abelian categories, then Wakamatsu tilting (resp. weak support tau-tilting) subcategories in A and C can induce Waka…
Several results on exact sequences in categories of modules over trusses
Yongduo Wang, Dengke Jia, Jian He +1
Categorical aspects of the theory of modules over trusses were studied in recent years. The snake lemma and the nine lemma in categories of modules over trusses are formulated in t…
Gorenstein modules and Auslander categories
Dejun Wu, Yongduo Wang
In this paper, some new characterizations on Gorenstein projective, injective and flat modules over commutative noetherian local ring are given.
A generalization of supplemented modules
Yongduo Wang
Let be a left module over a ring and an ideal of . is called an -supplemented module (finitely -supplemented module) if for every submodule (finitely gener…
Characterizations of I-semiregular and I-semiperfect rings
Yongduo Wang
Let be a left module over a ring and an ideal of . We call a (locally)projective -cover of if is an epimorphism from to , is (locally)…
When an -closed submodule is a direct summand
Yongduo Wang, Dejun Wu
It is well known that a direct sum of CLS-modules is not, in general, a CLS-module. It is proved that if , where and are CLS-modules such that an…
On a question of Mohamed and Müller
Yongduo Wang, Dejun Wu
A module is called H-supplemented if for every submodule of there is a direct summand of such that holds if and only if for any submodule …
