Voronoi diagrams of algebraic varieties under polyhedral norms
Adrian Becedas, Kathlén Kohn, Lorenzo Venturello
We study Voronoi diagrams of manifolds and varieties with respect to polyhedral norms. We provide upper and lower bounds on the dimensions of Voronoi cells. For algebraic varieties…
Equations of tensor eigenschemes
Valentina Beorchia, Francesco Galuppi, Lorenzo Venturello
We study schemes of tensor eigenvectors from an algebraic and geometric viewpoint. We characterize determinantal defining equations of such eigenschemes via linear equations in the…
On flag spheres with few equators
Lorenzo Venturello
In this note we construct a flag simplicial -sphere with the following properties: - is not a suspension; - has no edge that can be contracted to obtain another flag…
On the gamma-vector of symmetric edge polytopes
Alessio D'Alì, Martina Juhnke-Kubitzke, Daniel Köhne +1
We study -vectors associated with -vectors of symmetric edge polytopes both from a deterministic and a probabilistic point of view. On the deterministic side, we prove nonn…
