Abstract:A silting theorem was established by Buan and Zhou as a generalisation of the classical tilting theorem of Brenner and Butler. In this paper, we give an alternative proof of the theorem by using differential graded algebras.
Keywords:2-Term silting complex  Differential graded algebra  Torsion pair
