Burr's stronger finite-characterization conjecture for Ramsey-minimal graph families
Burr's stronger finite-characterization conjecture for Ramsey-minimal graph families
Let and be graphs, and let denote the family of Ramsey-minimal graphs for the pair . A matching is a graph whose connected components are all isomorphic to ; denotes the star with leaves. Burr's conjecture. The family is finite if and only if either one of and is a matching, or both and are of the form with a positive odd integer and . This proposed characterization is stronger than the two 1981 one-sided statements. It is false, as indicated by the paper's status evidence that Burr's stronger survey conjecture is disproved.
