Complete bipartite graphsAn acyclic edge-coloring of a graph is a proper edge-coloring without bichromatic (2-colored) cycles. The acyclic chromatic index of a graph G, denoted by a'(G), is the least integer k such that G admits an acyclic edge-coloring using k colors. Let Delta = ...
complete bipartite graph Wikipedia [kəm¦plēt bī′pär‚tīt ‚graf] (mathematics) A graph whose vertices can be partitioned into two sets such that every edge joins a vertex in one set with a vertex in the other, and each vertex in one set is joined to each vertex in the ...
Let G be a simple m×n bipartite graph with m≥n. We prove that if the minimum degree of G satisfies δ(G)≥m/2+1, then G is bipanconnected: for every pair of vertices x,y, and for every appropriate integer 2≤≤2n, there is an x,y-path ... Paul Erds,AL Rubin,H Taylor ...
In particular, if T is a tree of order m 3, then r(T, G) = 1 + ( m - 1)( n - 2). G Chartrand,RJ Gould,AD Polimeni - 《Journal of Graph Theory》 被引量: 5发表: 1980年 Ramsey Numbers of Some Bipartite Graphs Versus Complete Graphs The Ramsey number r(H, K n ) is ...
