摘要
Given t distinct colors, we order the t subsets of t - 1 colors in some arbitrary manner. Let G(1), G(2), ..., G(t) be graphs. The (t - 1)-chromatic Ramsey number, denoted by r(t-1)(t) (G(1), G(2), .., G(t)), is defined to be the least number n such that if the edges of the complete graph K-n are colored in any fashion with t colors, then for some i the subgraph whose edges are colored with the ith subset of colors contains a Gt. In this paper, we find the value of r(4)(5) (G(1), G(2), ... G(5)) when each Gt is a path.
