Gorenstein flat-cotorsion modules over tensor rings

Yongyun Qin, Chaobin Yin

Let $T_{R} (M)$ be a tensor ring, where $R$ is a ring and $M$ is an $N$ -nilpotent $R$ -bimodule. Under certain conditions, we characterize the Gorenstein flat-cotorsion modules over $T…

Gluing of cotorsion pairs via recollements of abelian categories

Jinrui Yang, Yongyun Qin

Let $(A^{^{'}}, A, A^{^{''}}, i^{*}, i_{*}, i^{!}, j_{!}, j^{*}, j_{*})$ be a recollement of abelian categories. Suppose that we are given two cotorsion pairs $({\…

ICE-closed subcategories and epibricks over recollements

Jinrui Yang, Yongyun Qin

Let $(A^{^{'}}, A, A^{^{''}}, i^{*}, i_{*}, i_{!}, j_{!}, j^{*}, j_{*})$ be a recollement of abelian categories. We proved that every ICE-closed subcategory (resp.…
