Effective Computation of Mutation Paths and Generators of Cluster Automorphism Groups
Jindong Zhao, Haiyan Zhu
In this paper, we improve the marked-vertex strategy introduced by Fu and Liang, and design the algorithm to compute all mutation paths and generator elements of cluster automorphi…
Chains of model structures arising from cotorsion pairs on extriangulated categories
Dandan Sun, Xiaoyan Yang, Dongdong Zhang +2
The main aim of this paper is to study chains of model structures arising from cotorsion pairs in extriangulated categories. Starting with a hereditary Hovey triple, we construct f…
Frobenius extensions about centralizer matrix algebras
Qikai Wang, Haiyan Zhu
This paper investigates the conditions under which the centralizer algebra of a matrix is a (separable) Frobenius extension of the base algebra . For a…
Intersection of complete cotorsion pairs
Qikai Wang, Haiyan Zhu
Given two (hereditary) complete cotorsion pairs and in an exact category with …

Qikai Wang, Haiyan Zhu
Let be a recollement of triangulated categories.A complete ideal cotorsion pair in induces complete ideal cotorsion pairs i…
Ideal approximation theory in Frobenius categories
Dandan Sun, Zhongsheng Tan, Qikai Wang +1
Let be a Frobenius category and the full subcategory consisting of projective objects. The relations between special precovering (resp., precovering) ideals in $…
