Abstract
Let be an abelian category and be the Happel-Reiten-Smal{\o} tilt of with respect to a torsion pair. We give necessary and sufficient conditions for the existence of a derived equivalence between and , which is compatible with the inclusion of into the derived category of . In particular, any splitting torsion pair induces a derived equivalence. We prove that for the realization functor of any bounded -structure, its denseness implies its fully-faithfulness.
