Simplex faces and quadratic toric ideals of lattice polytopes
Aki Mori, Hidefumi Ohsugi
We say that a convex polytope has the clique-face property if every clique in its 1-skeleton is the vertex set of a face. We establish this property as a geometric necessary condit…

Two-Dimensional Faces of Order and Chain Polytopes
Ragnar Freij-Hollanti, Teemu Lundström, Teemu Lundström +1
We give an explicit combinatorial description of the two-dimensional faces of both the order polytope and the chain polytope of a partially ordere…

Triangular faces of the order and chain polytope of a maximal ranked poset
Aki Mori
Let and denote the order polytope and chain polytope, respectively, associated with a finite poset . We prove the following result: if is a…
