Letc: [ω]2→r. A path of colorjis a listing (possibly empty) of integers {a0,a1,a2...} such that, for alli≥ 0, ifai+1exists thenc(ai,ai+1) =j. A empty list can be a path of any color. A singleton can be a path of any color. Paths might be finite or infinite. The color is determined for paths of more than one node. Improving on a result of Erdős, in 1978, Rado published a theorem which impliesRado Path Decomposition:Let c: [ω]2→r. Then, for each j < r, there is a path of color j such that these r paths (as sets) partition ω (so they are pairwise disjoint sets and their union is everything).Here we will provide some results and proofs which allow us to analyze the effective content of this theorem.
