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…
