Planar Ramsey numbers for cycles

چکیده
For two given graphs G and H the planar Ramsey number PR(G,H) is the smallest integer n such that every planar graph F on n vertices either contains a copy of G or its complement contains a copy H . By studying the existence of subhamiltonian cycles in complements of sparse graphs, we determine all planar Ramsey numbers for pairs of cycles.

Planar Ramsey Numbers for Small Graphs
Given two graphs G1 and G2, the planar Ramsey number PR(G1, G2) is the smallest integer n such that every planar graph on n vertices either contains a copy of G1 or its complement contains a copy of G2. So far, the planar Ramsey numbers have been determined, when both, G1 and G2 are complete graphs or both are cycles. By combining computer search with some theoretical results, in this paper we ...
متن کاملA Note on Planar Ramsey Numbers for a Triangle Versus Wheels
We assume that the reader is familiar with standard graph-theoretic terminology and refer the readers to Bondy and Murty (2008) for any concept and notation that is not defined here. In this paper, we consider simple, undirected graphs. Given two graphsG andH , the Ramsey numberR(G,H) is the smallest integer n such that every graph F on n vertices contains a copy of G, or its complement F conta...
متن کاملZarankiewicz Numbers and Bipartite Ramsey Numbers
The Zarankiewicz number z(b; s) is the maximum size of a subgraph of Kb,b which does not contain Ks,s as a subgraph. The two-color bipartite Ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of Kb,b with two colors contains a Ks,s in the rst color or a Kt,t in the second color.In this work, we design and exploit a computational method for bounding and computing...
متن کاملRamsey numbers of ordered graphs
An ordered graph G< is a graph G with vertices ordered by the linear ordering <. The ordered Ramsey number R(G<, c) is the minimum number N such that every ordered complete graph with c-colored edges and at least N vertices contains a monochromatic copy of G<. For unordered graphs it is known that Ramsey numbers of graphs with degrees bounded by a constant are linear with respect to the number ...
متن کاملPlanar Ramsey Numbers
The planar Ramsey number PR(G, H) is defined as the smallest integer n for which any 2-colouring of edges of Kn with red and blue, where red edges induce a planar graph, leads to either a red copy of G, or a blue H. In this note we study the weak induced version of the planar Ramsey number in the case when the second graph is complete.
