Ramsey-type problem for an almost monochromatic K_4

Combinatorics 2007-10-31 v1

Abstract

In this short note we prove that there is a constant cc such that every k-edge-coloring of the complete graph K_n with n > 2^{ck} contains a K_4 whose edges receive at most two colors. This improves on a result of Kostochka and Mubayi, and is the first exponential bound for this problem.
