Wasserstein distance to independence models

TÖ Çelik, A Jamneshan, G Montúfar, B Sturmfels… - Journal of symbolic …, 2021 - Elsevier

The -Polynomials of Locally Anti-Blocking Lattice Polytopes and Their -Positivity

H Ohsugi, A Tsuchiya - Discrete & Computational Geometry, 2021 - Springer
A lattice polytope P ⊂ R^ d P⊂ R d is called a locally anti-blocking polytope if for any closed
orthant\mathbb R^ d_ ε R ε d in R^ d R d, P ∩ R^ d_ ε P∩ R ε d is unimodularly equivalent …

Ehrhart theory of symmetric edge polytopes via ribbon structures

T Kálmán, L Tóthmérész - arXiv preprint arXiv:2201.10501, 2022 - arxiv.org
Using a ribbon structure of the graph, we construct a dissection of the symmetric edge
polytope of a graph into unimodular simplices. Our dissection is shellable, and one can …
