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.

On cohomological and K-theoretical Hall algebras of symmetric quivers

Valery Lunts, Špela Špenko, Michel Van den Bergh

We give a brief review of the cohomological Hall algebra CoHA $H$ and the K-theoretical Hall algebra KHA $R$ associated to quivers. In the case of symmetric qui…
