Locally anti-blocking -polytopes for flow polytopes
Jonah Berggren, Benjamin Braun, Alvaro Cornejo +6
Given an acyclic directed graph (DAG), the space of strength one flows is a lattice polytope called the flow polytope of the DAG. If the DAG admits an ample framing, then the flow…

Permutation Flows I: Triangulations of Flow Polytopes (Research Announcement)
Rafael S. González D'León, Christopher R. H. Hanusa, Martha Yip
We introduce a new broadly unifying family of combinatorial objects, which we call permutation flows, associated to an acyclic directed graph together with a framing . This…
