$\omega$-left approximation dimensions under Stable equivalence

Representation Theory 2025-07-15 v1

Abstract

In this paper, we investigate some transfer properties of ω\omega-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.
