Running Complete bipartite graphs. A complete bipartite graph is a graph having the property that the vertices of the graph can be divided into two groups A and B and each vertex in A is adjacent to each vertex in B, as shown in Fig 5-64 . Two vertices in A are never adjacent, and neither are two vertices in B. Let m and n denote the number of vertices in A and B, respectively, and assume m ≤ n . Figure 5-64 a. Describe all the possible values of m and n for which the complete bipartite graph has an Euler circuit. ( Hint: There are infinitely many values of m and n. ) b. Describe all the possible values of m and n for which the complete bipartite graph has an Euler path.
