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

-vector inequalities for order and chain polytopes
Ragnar Freij-Hollanti, Teemu Lundström
The order and chain polytopes are two 0/1-polytopes constructed from a finite poset. In this paper, we study the -vectors of these polytopes. We investigate how the order and ch…
