On the Minimal Edge Density of $K_{4}$ -free 6-critical Graphs

Wenbo Gao, Luke Postle

Kostochka and Yancey resolved a famous conjecture of Ore on the asymptotic density of $k$ -critical graphs by proving that every $k$ -critical graph $G$ satisfies $|E(G)| \geq (\frac…

Highly symmetric matroids, the strong Rayleigh property, and sums of squares

Wenbo Gao, David G. Wagner

We investigate the strong Rayleigh property of matroids for which the basis enumerating polynomial is invariant under a Young subgroup of the symmetric group on the ground set. In…
