Torsion pairs and filtrations in abelian categories with tilting objects
Torsion pairs and filtrations in abelian categories with tilting objects
Given a noetherian abelian k-category [Formula: see text] of finite homological dimension, with a tilting object T of projective dimension 2, the abelian category [Formula: see text] and the abelian category of modules over End (T) op are related by a sequence of two tilts; we give an explicit description …
