This chapter presents the terminology and concepts of graph theory, and describes basic matrix operations that are used in social network analysis. Both graph theory and matrix operations have served as the foundations of many concepts in the analysis of social networks (Hage and Harary 1983; Harary, Norman, and Cartwright 1965).

WebTIn this paper, we characterize the graphs G and H for which the product of the adjacency matrices A (G)A (H) is graphical. We continue to define matrix product of two graphs and study a few properties of the same product. Further, we consider the case of regular graphs to study the graphical property of the product of adjacency matrices. 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.
