Let\(G\) be a graph with vertex set\(V (G)\) and edge set\(E (G)\). Let\(d_i\) be the degree of
the vertex\(v_i\in V (G)\). The first and second Zagreb indices,\(M_1=\sum_ {v_i\in V (G)} d_i …

The concept of Sombor index (SO) was recently introduced by Gutman in the chemical
graph theory. It is a vertex-degree-based topological index and is denoted by Sombor index …

In 1972, within a study of the structure-dependency of total π π-electron energy (EE), it was
shown that EE depends on the sum of squares of the vertex degrees of the molecular graph …
