The complete graph Kn has an adjacency matrix equal to A = J ¡ I, where J is the all-1’s matrix and I is the identity. The rank of J is 1, i.e. there is one nonzero eigenvalue equal to n (with an eigenvector 1 = (1;1;:::;1)). All the remaining eigenvalues are 0. Subtracting the identity shifts all eigenvalues by ¡1, because Ax = (J ¡ I ... 1. Null Graph: A null graph is defined as a graph which consists only the isolated vertices. Example: The graph shown in fig is a null graph, and the vertices are isolated vertices. 2. Undirected Graphs: An Undirected graph G consists of a set of vertices, V and a set of edge E. The edge set contains the unordered pair of vertices.This is because you can choose k k other nodes out of the remaining P − 2 P − 2 in (P−2)! (P−2−k)!k! ( P − 2)! ( P − 2 − k)! k! ways, and then you can put those k k nodes in any order in the path. So the total number of paths is given by adding together these values for all possible k k, i.e. ∑k=0P−2 (P − 2)!Determining whether a graph can be colored with 2 colors is in P, but with 3 colors is NP-complete, even when restricted to planar graphs. Determining if a graph is a cycle or is bipartite is very easy (in L ), but finding a maximum bipartite or a maximum cycle subgraph is NP-complete.Definition: Complete Graph.
