If you have a question about this talk, please contact Eoin Long. A graph is k-critical if it has chromatic number k and every proper subgraph is (k-1)-colorable. The density of critical graphs has been extensively studied. We present an improvement on the best known lower bound for the density of critical graphs without large cliques. We also discuss a connection to a possible generalization of Reed’s Conjecture. Joint work with Luke Postle.
