β¦ Synopsis
In 1929, Ramsey proved a theorem guaranteeing that if G1, G,, . . . , Gk are graphs, then there exists an integer r so that if the edges of EC, are colored in any fashion with k colors a monochromatic G* in color i exists for some i Harary and Prins suggested the problem of deciding the minimum number of monochromatic Gi in any such coloring. It is the purpose of this paper to establish this minimum number in the case when G, are stars for each i.
