On the spectrum and energy of singular graphs
Energy of a graph is defined as the sum of the absolute values of the eigenvalues of the adjacency matrix A(G)of a graph Gand is denoted by E(G). The graph G with n vertices is called nonhypoenergetic if E(G)≥nand hypoenergetic if E(G)<n. Singular graphs are graphs with nullity η(G)>0. In this...
