AbstractGiven a graph G= (V, E), the Inverse sum Indeg Index of G, ISI(G) is defined as , where Eis the set of edges of Gand dis the degree of the vertex u∈V. In this paper, we obtain some bounds of ISIindex in terms of some known topological indices. A modification of classical adjacency matrix corresponding to ISIindex is proposed and various spectral properties are studied. The new concepts of ISIenergy and ISIEstrada index are introduced. We also obtain some bounds of these new graph invariants. |
