WebIn graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. WebWe also show that a matrix derived from the binomial incidence matrix satisfies a result in graph theory which relates incidence matrix of a graph and adjacency matrix of its line graph. We extend the concept of {"}twin vertices{"}in the theory of graphs to semigraph theory, and characterize them.

WebSep 4, 2015 · The incidence matrix of a digraph (directed graph) has been defined as follows. The values for Mij (elements of the incidence matrix) { If the arc head is on the vertex => -1 If the arc tail is on the vertex => +1 Otherwise => 0 } This is how the incidence matrix for a digraph has been defined.

Arrows indicated in the branches of a graph result in an oriented or a directed graph. These arrows are the indication for the current flow or voltage rise in the network.
