Let G be a bipartite graph, with k|e(G). The zero-sum bipartite Ramsey number B(G, Z k ) is the smallest integer t such that in every Z k -coloring of the edges of K t,t , there is a zero-sum mod k copy of G in K t,t . In this article we give the first proof that determines B(G, Z 2 ) for all possib
