Singular equivalences induced by homological epimorphisms

Published 29 Jul 2011 in math.RA and math.RT | (1107.5922v1)

Abstract: We prove that a certain homological epimorphism between two algebras induces a triangle equivalence between their singularity categories. Applying the result to a construction of matrix algebras, we describe the singularity categories of some non-Gorenstein algebras.
