Left Schur subcategories in recollements
Yingying Zhang, Dajun Song
Recently left Schur subcategories in a length abelian category were introduced by Enomoto, which unify torsion-free classes and wide subcategories. In this paper, we give a constru…
The derived dimensions and representation distances of artin algebras
Junling Zheng, Yingying Zhang
There is a well-known class of algebras called Igusa-Todorov algebras which were introduced in relation to finitistic dimension conjecture. As a generalization of Igusa-Todorov alg…
Mutation of Brauer configuration algebras
Toshitaka Aoki, Yingying Zhang
For Brauer graph algebras, tilting mutation is compatible with flip of Brauer graphs. The aim of this paper is to generalize this result to the class of Brauer configuration algebr…
Applications of Gorenstein projective -rigid modules
Hui Liu, Xiaojin Zhang, Yingying Zhang
We first introduce the notion of --tilting free algebras as the generalization of -free algebras and show the homological properties of --tilting free algebras. T…
