Column convex matrices, $G$-cyclic orders, and flow polytopes

Rafael S. González D'León, Christopher R. H. Hanusa, Alejandro H. Morales +1

We study polytopes defined by inequalities of the form ${\sum }_{i\in I}{z}_i\le 1$ for $I\subseteq [d]$ and nonnegative $z_i$ where the inequalities can be reordered into a matrix…
