关于内射模的倾斜模和优势维数

Tilting modules and dominant dimension with respect to injective modules

Takahide Adachi, Mayu Tsukamoto

摘要:

本文研究了有限投射维数的倾斜模与关于内射模的控制维数之间的关系,推广了Crawley-Boevey-Sauter,Nguyen-Reiten-Todorov-Zhu和Pressland-Sauter的结果.利用倾斜模的存在性刻画了几乎$n$ -Auslander-Gorenstein代数和几乎$n$ -Auslander代数.作为应用,通过比较几乎$1$ -Auslander代数的倾斜模和特征倾斜模,给出了几乎$1$ -Auslander代数是强拟遗传的一个充分条件.

英文摘要:

In this paper, we study a relationship between tilting modules with finite projective dimension and dominant dimension with respect to injective modules as a generalization of results of Crawley-Boevey-Sauter, Nguyen-Reiten-Todorov-Zhu and Pressland-Sauter. Moreover, we give characterizations of almost $n$-Auslander-Gorenstein algebras and almost $n$-Auslander algebras by the existence of tilting modules. As an application, we describe a sufficient condition for almost $1$-Auslander algebras to be strongly quasi-hereditary by comparing such tilting modules and characteristic tilting modules.
