Yushan Qu, Jon Lee
Staircase simplices are the simplices of the standard (Freudenthal--Kuhn) triangulation of and of Stanley's triangulations of order polytopes. We study the facet normals…

On the facets of the Cayley polytope of Stanley's triangulation
Yushan Qu, Jon Lee
Disjunctions over the cells of a triangulation arise in formulations of piecewise-linear functions. For a poset on , we study the convex hull of the simplices of Stanl…
