List of Problems

Martina Juhnke-Kubitzke, Rosa M. Miró-Roig

The study of the Lefschetz properties of Artinian graded algebras was motivated by the hard Lefschetz theorem for a smooth complex projective variety, a breakthrough in algebraic t…

Two subspace methods for frequency sparse graph signals

Tarek Emmrich, Martina Juhnke-Kubitzke, Stefan Kunis

We study signals that are sparse in graph spectral domain and develop explicit algorithms to reconstruct the support set as well as partial components from samples on few vertices…

On a generalization of symmetric edge polytopes to regular matroids

Alessio D'Alì, Martina Juhnke-Kubitzke, Melissa Koch

Starting from any finite simple graph, one can build a reflexive polytope known as a symmetric edge polytope. The first goal of this paper is to show that symmetric edge polytopes…

Laplacian polytopes of simplicial complexes

Martina Juhnke-Kubitzke, Daniel Köhne

Given a (finite) simplicial complex, we define its -th Laplacian polytope as the convex hull of the columns of its -th Laplacian matrix. This extends Laplacian simplices of f…

Alexander duals of symmetric simplicial complexes and Stanley-Reisner Ideals

Ayah Almousa, Kaitlin Bruegge, Martina Juhnke-Kubitzke +2

Given an ascending chain of $\Sym$-invariant squarefree monomial ideals, we study the corresponding chain of Alexander duals .…

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…
