A complete digraph is a directed graph in which every pair of distinct vertices is connected by a pair of unique edges .Section 4.3 Planar Graphs Investigate! When a connected graph can be drawn without any edges crossing, it is called planar. When a planar graph is drawn in this way, it divides the plane into regions called faces. Draw, if possible, two different planar graphs with the same number of vertices, edges, and faces.Definition 5.8.1 A proper coloring of a graph is an assignment of colors to the vertices of the graph so that no two adjacent vertices have the same color. . Usually we drop the word "proper'' unless other types of coloring are also under discussion. Of course, the "colors'' don't have to be actual colors; they can be any distinct labels ...A complete classification of the 1-planar complete graphs, complete bipartite graphs, and more generally complete multipartite graphs is known. Every complete bipartite graph of the form K 2,n is 1-planar (even planar), as is every complete tripartite graph of the form K 1,1,n. Other than these infinite sets of examples, the only complete ...If loops are allowed. The relation between matrices is. A + A˜ = J A + A ~ = J. where J = 11T J = 1 1 T is the all-ones matrix. The first consequence is that the sum of the eigenvalues of A A and A˜ A ~ equals |V| | V | where V V is the set of vertices. A second consequence concerns multiple eigenvalues.The way to identify a spanning subgraph of K3,4 K 3, 4 is that every vertex in the vertex set has degree at least one, which means these are just the graphs that cannot possibly be counted by Z(Qa,b) Z ( Q a, b) with (a, b) ≠ (3, 4) ( a, b) ≠ ( 3, 4) because of the missing vertices.14.

(If a pair (w,v) can occur several times in E we call the structure ...I can see why you would think that. For n=5 (say a,b,c,d,e) there are in fact n! unique permutations of those letters. However, the number of cycles of a graph is different from the number of permutations in a string, because of duplicates -- there are many different permutations that generate the same identical cycle.
