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…
The representation theory of noncommutative
Theo Raedschelders, Michel Van den Bergh
In our companion paper "The Manin Hopf algebra of a Koszul Artin-Schelter regular algebra is quasi-hereditary" we used the Tannaka-Krein formalism to study the universal coacting H…
The Manin Hopf algebra of a Koszul Artin-Schelter regular algebra is quasi-hereditary
Theo Raedschelders, Michel Van den Bergh
For any Koszul Artin-Schelter regular algebra A, we consider a version of the universal Hopf algebra aut(A) coacting on A, introduced by Manin. To study the representations (i.e. f…
On the derived category of Grassmannians in arbitrary characteristic
Ragnar-Olaf Buchweitz, Graham J. Leuschke, Michel Van den Bergh
In this paper we consider Grassmannians in arbitrary characteristic. Generalizing Kapranov's well-known characteristic-zero results we construct dual exceptional collections on the…
