The numbers of edges of the order polytope and the chain poyltope of a finite partially ordered set

Takayuki Hibi, Nan Li, Yoshimi Sahara +1

Let $P$ be an arbitrary finite partially ordered set. It will be proved that the number of edges of the order polytope $O (P)$ is equal to that of the chain polytope ${\m…

On dimensions of tangent cones in limit spaces with lower Ricci curvature bounds

Vitali Kapovitch, Nan Li

We show that if $X$ is a limit of $n$ -dimensional Riemannian manifolds with Ricci curvature bounded below and $γ$ is a limit geodesic in $X$ then along the interior of $γ$ same sca…

Order-Chain Polytopes

Takayuki Hibi, Nan Li, Teresa Xueshan Li +2

Given two families $X$ and $Y$ of integral polytopes with nice combinatorial and algebraic properties, a natural way to generate new class of polytopes is to take the intersection…
