The Ramsey number r (H) of a graph H is the minimum integer n such that any two-coloring of the edges of the complete graph K n contains a monochromatic copy of H. While this definition only asks for a single monochromatic copy of H, it is often the case that every two-edge-coloring of the complete graph on r (H) vertices contains many monochromatic copies of H. The minimum number of such copies over all two-colorings of K r (H) will be referred to as the threshold Ramsey multiplicity of H. Addressing a problem of Harary and Prins, who were the first to systematically study this quantity, we show that there is a positive constant c such that the threshold Ramsey multiplicity of a path or an even cycle on k vertices is at least (c k) k. This bound is tight up to the constant c. We prove a similar result for odd cycles in a companion paper.
