A Lovász-Kneser theorem for triangulations

Anton Molnar, Cosmin Pohoata, Michael Zheng +1

We show that the Kneser graph of triangulations of a convex $n$ -gon has chromatic number $n - 2$ .

Hypergraphic zonotopes and acyclohedra

Cosmin Pohoata, Daniel G. Zhu

We introduce a higher-uniformity analogue of graphic zonotopes and permutohedra. Specifically, given a $(d + 1)$ -uniform hypergraph $H$ , we define its hypergraphic zonotope $\mathcal…

Series-parallel graphs and hypercube degeneracy

Daniel G. Zhu

Several recent works have identified patterns that must exist in dense subsets of either the vertices or the edges of a large hypercube. We introduce a framework, based on the conc…
