Graph theory theorems

WebIn the language of graph theory, the Ramsey number is the minimum number of vertices, v = R(m, n), such that all undirected simple graphs of order v, contain a clique of order m, or an independent set of order n. Ramsey's theorem states that such a number exists for all m and n . By symmetry, it is true that R(m, n) = R(n, m). Weband the minimum degree of a graph is denoted by (G). Vizing’s Theorem is the central theorem of edge-chromatic graph theory, since it provides an upper and lower bound for the chromatic index ˜0(G) of any graph G. Moreover, the upper and lower bound have a di erence of 1. That is, for all nite, simple graphs G, ( G) ˜0(G) ( G) + 1.
