Ramsey-Type Results for Gallai Colorings - WPI

WebJul 21, 2011 · Abstract. Consider the graph consisting of a triangle with a pendant edge. We describe the structure of rainbow -free edge colorings of a complete graph and provide some corresponding Gallai–Ramsey results. In particular, we extend a result of Gallai to find a partition of the vertices of a rainbow -free colored complete graph with a limited ... WebLet h(n,p) be the minimum integer such that every edge-colouring of the complete graph of order n, using exactly h(n,p) colours, produces at least one cycle of order p having all its edges of different colours. In this paper the value of h(n,p) is determinated for n≥p≥3. As a corollary we obtain the equality which was conjectured by Erdös, Simonovits and Sós, 30 … WebOur result yields a unified proof for the Gallai-Ramsey number of all even cycles on at least four vertices.
