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…

Cotorsion pairs in comma categories

Yuan Yuan, Jian He, Dejun Wu

Let A and B be abelian categories with enough projective and injective objects, and T : A-B a left exact additive functor. Then one has a comma category (B*T). It is shown that If…

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…
