Stability of the path–path Ramsey number
For graphs \(G_1, G_2, \dots, G_r\) the Ramsey number \(R(G_1, G_2, \dots, G_r)\) is the smallest positive integer \(n\) such that if the edges of a complete graph \(K_n\) are partitioned into \(r\) disjoint colour classes giving \(r\) graphs \(H_1, H_2, \dots, H_r\), then at least one \(H_i\), \(1\leq i\leq r\), contains a subgraph isomorphic to \(G_i\
