Fano 4-fold quiver moduli from subspace quivers
Pieter Belmans, Markus Reineke
The paper classifies all Fano fourfolds that can be realized as moduli spaces of representations of subspace quivers, identifying exactly four such varieties and describing their g…
Brauer groups of resolved quiver moduli via gerbes
Pieter Belmans, Gianni Petrella, Sebastián Torres
We show that the Brauer group of any resolution of singularities of the moduli space of semistable quiver representations is trivial. We do this by extending the quiver-curve dicti…
Failure of Bott vanishing for (co)adjoint partial flag varieties
Pieter Belmans
Bott vanishing is a strong vanishing result for the cohomology of exterior powers of the cotangent bundle twisted by ample line bundles. Buch-Thomsen-Lauritzen-Mehta conjectured th…
A-D-E diagrams, Hodge--Tate hyperplane sections and semisimple quantum cohomology
Pieter Belmans, Sergey Galkin, Naichung Conan Leung +3
It is known that the semisimplicity of quantum cohomology implies the vanishing of off-diagonal Hodge numbers (Hodge--Tateness). We investigate which hyperplane sections of homogen…
The QuiverTools package for SageMath and Julia
Pieter Belmans, Hans Franzen, Gianni Petrella
We introduce QuiverTools, a new software package, available in both a SageMath and Julia version, to study quivers and their moduli spaces of representations. Its key features are…
