WebDegree matrix. In the mathematical field of algebraic graph theory, the degree matrix of an undirected graph is a diagonal matrix which contains information about the degree of each vertex —that is, the number of edges attached to each vertex. [1] It is used together with the adjacency matrix to construct the Laplacian matrix of a graph: the ... WebThe graph in Figure 6.2 has one source (node a) and no sinks. 6.1.2 Directed Walks, Paths, and Cycles The definitions for (directed) walks, paths, and cycles in a directed graph are similar to those for undirected graphs except that the direction of the edges need to be consistent with the order in which the walk is traversed.

WebThe degree of a node in an undirected graph is the number of edges incident on it; for directed graphs the indegree of a node is the number of edges leading into that node and its outdegree, the number of edges leading away from it (see also Figures 6.1 and 6.2). A path (or chain) on an undirected graph is a sequence of adjacent edges and nodes.

WebHandshaking lemma: if the number of vertices with odd degrees is odd, it is not a simple graph. Order the degree sequence into descending order, like 3 2 2 1; Remove the leftmost degree: 2 2 1 , and call the first degree k, so k=3 here; Subtract 1 from the leftmost k degrees: 1 1 0; If any of the degrees are negative, it is not a simple graph.
