James Davies gave a talk on the 𝜒-boundedness and the strong Erdős-Hajnal property of proper pivot-minor-closed classes of graphs at the Discrete Math Seminar

On April 11, 2023, James Davies from the University of Cambridge gave a talk at the Discrete Math Seminar on his two theorems stating that proper pivot-minor-closed classes of graphs are 𝜒-bounded and have the strong Erdős-Hajnal property. The title of his talk is “two structural results for pivot-minors.”
