An equivalence linking CM-types $A_{\infty}$ and $D_{\infty}$

Charley Cummings, Sira Gratz, Ellen Kirkman +3

We show that, for a specific grading, the stable categories of graded maximal Cohen-Macaulay modules over hypersurfaces of type $A_{\infty}$ and $D_{\infty}$ are equivalent.

Metric completions of discrete cluster categories

Charley Cummings, Sira Gratz

Neeman shows that the completion of a triangulated category with respect to a good metric yields a triangulated category. We compute completions of discrete cluster categories with…
