A Hochschild-Kostant-Rosenberg type theorem for coherent matrix factorizations

Abstract

In this article, we prove a Hochschild-Kostant-Rosenberg type theorem for the category of coherent matrix factorizations associated to a Landau-Ginzburg model (X,f), where X is a quasi-smooth derived Deligne-Mumford stack over an algebraically closed field of characteristic 0.
