On the Iyama–Yoshino reduction in extriangulated categories

  • Mindy Y. Huerta

摘要

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.
