Equivalence classes of Wakamatsu tilting modules and preenveloping and precovering subcategories (2512.11600v1)
Published 12 Dec 2025 in math.RT
Abstract: Let R be an associative ring with identity. We introduce an equivalence relation on the class of Wakamatsu tilting right R modules. By using this equivalence relation, we extend the Mantese Reiten theorems from the setting of Artin algebras to that of arbitrary associative rings.
