Webmatrix B(G)ofG is the m⇥n matrix whose entries bij are given by bij= (+1 if ej = {vi,vk} for some k 0otherwise. Unlike the case of directed graphs, the entries in the incidence matrix of a graph (undirected) are nonnegative. We usually write B instead of B(G). The notion of adjacency matrix is basically the same for directed or undirected graphs. WebNov 18, 2024 · A graph denoted by G= (V,E) consists of a set V of vertices and a set E of edges between the vertices. A graph is simple when the number of edges between any of its vertices is at most 1 and it has no self-loops around any of its vertices. We will consider mostly simple graphs in this text.
