Résumé

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