Title
Two-colorings with many monochromatic cliques in both colors
Abstract
Color the edges of the n-vertex complete graph in red and blue, and suppose that red k-cliques are fewer than blue k-cliques. We show that the number of red k-cliques is always less than c"kn^k, where c"k@?(0,1) is the unique root of the equation z^k=(1-z)^k+kz(1-z)^k^-^1. On the other hand, we construct a coloring in which there are at least c"kn^k-O(n^k^-^1) red k-cliques and at least the same number of blue k-cliques.
