WebProof. Was given in class by induction using the fact that A(G)k = A(G)k−1A(G) and using the deﬁnition of matrix multiplication. As a special case, the diagonal entry A(G)k ii is the number of closed walks from vi back to itself with length k. The sum of the diagonal entries of A(G)k is the total number of closed walks of length k in graph G. WebA graph is connected if any two vertices of the graph are connected by a path; while a graph is disconnected if at least two vertices of the graph are not connected by a path. If a graph G is disconnected, then every maximal connected subgraph of G is called a connected component of the graph G.

WebIn graph theory, Brooks' theorem states a relationship between the maximum degree of a graph and its chromatic number.According to the theorem, in a connected graph in which every vertex has at most Δ neighbors, the vertices can be colored with only Δ colors, except for two cases, complete graphs and cycle graphs of odd length, which require Δ + 1 colors.
