Order and chain polytopes of maximal ranked posets
arXiv (Cornell University)(2023)
摘要
For a class of posets we establish that the f-vector of the chain polytope dominates the f-vector of the order polytope. This supports a conjecture of Hibi and Li. Our proof reveals a combinatorial description of the faces of the corresponding chain polytopes.
