Abstract

For a noetherian ring Λ\Lambda, the stabilization functor in the sense of Krause yields an embedding of the singularity category of Λ\Lambda into the homotopy category of acyclic complexes of injective Λ\Lambda-modules. When Λ\Lambda contains a semisimple artinian subring EE, we give an explicit description of the stabilization functor using the Hom complexes in the EE-relative singular Yoneda dg category of Λ\Lambda.
