As a general framework for the studies of *t*-structures on triangulated categories and torsion pairs in abelian categories, we introduce the notions of extriangulated categories with negative first extensions and *s*-torsion pairs. We define a heart of an interval in the poset of *s*-torsion pairs, which naturally becomes an extriangulated... Show more
