On Cohen-Macaulay modules over non-commutative surface singularities

preprint2013arXivOpen access

Abstract

We generalize the results of Kahn about a correspondence between Cohen-Macaulay modules and vector bundles to non-commutative surface singularities. As an application, we give examples of non-commutative surface singularities which are not Cohen-Macaulay finite, but are Cohen-Macaulay tame.
