A graph in which atoms are taken as vertices and bonds can be shown by edges is called a
molecular graph. For such graphs we can find the indices showing their bioactivity as well as …

For a connected graph, the second Zagreb eccentricity index (ξ 2) is defined as the sum of
the products of the eccentricities of pairs of adjacent vertices. Let G (n, m, d) be the class of n …

The variable connectivity index, introduced by the chemist Milan Randić in the first quarter of
1990s, for a graph G is defined as∑ vw∈ EG dv+ γ dw+ γ− 12/, where γ is a non‐negative …
