WebThe adjacency matrix has a total of 12 ones, which represents the number of edges in the graph. However, each edge is counted twice in the matrix, once for each of its endpoints. Therefore, the actual number of edges is 6. WebThe adjacency matrix of a signed network may not have a dominant eigenvalue. This means it is not clear which eigenvector should be used. In addition it is possible for the adjacency matrix to have repeated eigenvalues and hence multiple linearly independent eigenvectors. In this case certain centralities can be arbitrarily assigned.
