On the Iyama-Yoshino reduction in extriangulated categories

Representation Theory 2025-07-08 v2

Abstract

In this paper, we provide an interpretation of the existing reduction process for extriangulated categories in general. This process allows us to obtain a new category which, for well-known cases, admits a triangulated structure. We will show that in general this new category is extriangulated but not necessarily triangulated.
