Derived invariance of Hochschild-Mitchell (co)homology and one-point extensions

Mostrar todas las versiones(3)

In this article we prove derived invariance of Hochschild-Mitchell homology and cohomology and we extend to k-linear categories a result by Barot and Lenzing concerning derived equivalences and one-point extensions. We also prove the existence of a long exact sequence à la Happel and we give a gener...
