Cluster characters for 2-Calabi-Yau Frobenius extriangulated categories
Li Wang, Jiaqun Wei, Haicheng Zhang
We define the cluster characters for 2-Calabi-Yau Frobenius extriangulated categories with cluster tilting objects. This provides a unified framework of cluster characters in 2-Cal…
The Auslander-Reiten theory of the morphism category of projective modules
Rasool Hafezi, Jiaqun Wei
We investigate the structure of certain almost split sequences in , i.e., the category of morphisms between projective modules over an Artin algebra . The catego…
Distributivity in lattices of torsion classes over finite-dimensional algebras
Yongle Luo, Jiaqun Wei
Let be a basic finite-dimensional algebra and denote by the collection of all all torsion classes of . It has been proved in \cite{Demonet} that $\op…
Sincere silting modules and vanishing conditions
Jifen Liu, Jiaqun Wei
Let be a perfect ring and be an -module. We study characterizations of sincere modules, sincere silting modules and tilting modules in terms of various vanishing conditi…
Semibricks, torsion-free classes and the Jordan-Hölder property
Li Wang, Jiaqun Wei, Haicheng Zhang +1
Let be an extriangulated category and be a semibrick in . Let be the filtration subcategory generated by . We in…
Hall algebras of extriangulated categories
Li Wang, Jiaqun Wei, Haicheng Zhang
Recently, Nakaoka and Palu introduced a notion of extriangulated categories. This is a unification of exact categories and triangulated categories. In this paper, we generalize the…
