The reduced graphs, corresponding reduced adjacency matrices, and characteristic polynomial equations after the following vertices have been removed from the graph in Fig. 10(a): (a) vertex 2, p(λ)[A]−2, (b) vertex 3, p(λ)[A]−3 and (c) vertex 4, p(λ)[A]−4. (d) The original graph, adjacency matrix and the vertex subsets determined using characteristic polynomial equations. |
