A bipartite Ramsey number
Denote by \(br(G;k)\) the \(k\)-color bipartite Ramsey number of a bipartite graph \(G\), i.e. the minimum integer \(n\) such that in any \(k\)-coloring of the edges of \(K_{n,n}\) there is a monochromatic subgraph isomorphic to \(G\). In this note the author proved that \(br(C_ 4;3)=11\).
