Skew graded $(A_{\infty})$ hypersurface singularities

Kenta Ueyama

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 t…

Combinatorial study of stable categories of graded Cohen--Macaulay modules over skew quadric hypersurfaces

Akihiro Higashitani, Kenta Ueyama

In this paper, we present a new connection between representation theory of noncommutative hypersurfaces and combinatorics. Let $S$ be a graded ( $\pm 1$ )-skew polynomial algebra in…

On Knörrer periodicity for quadric hypersurfaces in skew projective spaces

Kenta Ueyama

We study the structure of the stable category $CM^{Z} (S / (f))$ of graded maximal Cohen-Macaulay module over $S / (f)$ where $S$ is a graded ( $\pm 1$ )-skew…
