Abstract

For a skew version of a graded (A)(A_\infty) hypersurface singularity AA, we study the stable category of graded maximal Cohen-Macaulay modules over AA. As a consequence, we see that AA has countably infinite Cohen-Macaulay representation type and is not a noncommutative graded isolated singularity.
