The 3-Color 2-Chromatic Gallai-Ramsey Number for Complete Graphs

Abstract

For 1≤ i≤ j≤ k, let gr32(Ki, Kj, Kk) be the least n∈ ℕ such that every rainbow triangle-free $3$-coloring of Kn (using red, blue, and green) contains a red/blue Ki, a red/green Kj, or a blue/green Kk. In this paper, we completely evaluate gr32(Ki, Kj, Kk) for all values of i, j, and k in which r(Ki,Kj) is known.

AB  - For 1≤ i≤ j≤ k, let gr^3_2(K_i, K_j, K_k) be the least n∈ ℕ such that every rainbow triangle-free $3$-coloring of K_n (using red, blue, and green) contains a red/blue K_i, a red/green K_j, or a blue/green K_k. In this paper, we completely evaluate gr^3_2(K_i, K_j, K_k) for all values of i, j, and k in which r(K_i,K_j) is known.
