Maximal Cohen-Macaulay modules over a noncommutative 2-dimensional singularity
arXiv:1906.06824
Abstract
We study properties of graded maximal Cohen-Macaulay modules over an N-graded locally finite, Auslander Gorenstein, and Cohen-Macaulay algebra of dimension two. As a consequence, we extend a part of McKay correspondence in dimension two to a more general setting.
