Skew graded $(A_\infty)$ hypersurface singularities

Published 12 Apr 2022 in math.RA and math.RT | (2204.05501v2)

Abstract: 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.
