稳定等价下的$ω$-左逼近维数

$ω$-left approximation dimensions under Stable equivalence

Juxiang Sun, Guoqiang Zhao, Junling Zheng

AI总结:

本文研究了无节点及半单直和项的稳定等价Artin代数模的$ω$-左逼近维数传递性质,并据此证明了基础Wakamatsu倾斜模的一一对应关系及该倾斜猜想的保持性。

摘要:

本文研究了既无节点也无半单直和项的稳定等价Artin代数的模的$ω$-左逼近维数的一些传递性质。作为应用,我们给出了基础(Wakamatsu)倾斜模之间的一一对应,并证明了Wakamatsu倾斜猜想在这些等价下是保持的。

英文摘要:

In this paper, we investigate some transfer properties of $ω$-left approximation dimensions of modules of stably equivalent Artin algebras having neither nodes nor semisimple direct summands. As applications, we give a one-to-one correspondence between basic (Wakamatsu) tilting modules, and prove that the Wakamatsu tilting conjecture is preserved under those equivalences.
