Homotopy categories of injective modules over derived discrete algebras
Abstract
We study the homotopy category K( A) of all injective modules over a finite dimensional algebra A with discrete derived category. We give a classification of the indecomposable objects of K( A) for any radical square zero self-injective algebra A. In particular, every indecomposable object is endofinite.
