Abstract
Given a pair of graphs and , the Ramsey number is the smallest such that every red-blue coloring of the edges of the complete graph contains a red copy of or a blue copy of . If graph is connected, it is well known and easy to show that , where is the chromatic number of and the size of the smallest color class in a -coloring of . A graph is called -good if . The notion of Ramsey goodness was introduced by Burr and Erd\H{o}s in 1983 and has been extensively studied since then. In this short note we prove that -vertex path is -good for all . This proves in a strong form a conjecture of Allen, Brightwell, and Skokan.
