Hearts of twin cotorsion pairs revisited: integral and abelian hearts (2306.16603v1)
Published 29 Jun 2023 in math.RT and math.CT
Abstract: Hearts of twin cotorsion pairs are shown to be quasi-abelian. But they are not always integral. In this article, we provide a sufficient and necessary condition for the hearts of twin cotorsion pairs being integral (resp. abelian).
