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