An equivalence linking CM-types and
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 and are equivalent.
Comparison of Cohomological and K-theoretical Hall algebra
Felix Küng, Špela Špenko
We give a more conceptual construction of a comparison algebra morphism from the K-theoretical Hall algebra to a twist of the cohomological Hall algebra associated to a symmetric q…
Homotopy Invariants for gradable finite dimensional algebras
Sira Gratz, Theo Raedschelders, Špela Špenko +1
We show that for a gradable finite dimensional algebra the perfect complexes and bounded derived category cannot be distinguished by homotopy invariants.
HMS symmetries of toric boundary divisors
Špela Špenko, Michel Van den Bergh
Let be a projective crepant resolution of a Gorenstein affine toric variety and let be the LG-model which is the Hori-Vafa mirror dual of . Let …
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 and the K-theoretical Hall algebra KHA associated to quivers. In the case of symmetric qui…
Catalan numbers, parking functions, permutahedra and noncommutative Hilbert schemes
Valery Lunts, Špela Špenko, Michel Van den Bergh
We find an explicit -equivariant bijection between the integral points in a certain zonotope in , combinatorially equivalent to the permutahedron, and the set of…
