Eccentric connectivity index: extremal graphs and values

Iranian journal of mathemathical chemistry, 2010
Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially

Extremal Values of the Sombor Index in Tricyclic Graphs

match Communications in Mathematical and in Computer Chemistry, 2023
Summary: A vertex-degree-based molecular structure descriptor was introduced by \textit{I. Gutman} [MATCH Commun. Math. Comput. Chem. 86, No. 1, 11--16 (2021; Zbl 1474.92154)], named the Sombor index. The Sombor index of a graph \(G\) is defined as \(SO(G)=\sum\limits_{uv\in E(G)} \sqrt{d_G(u)^2+d_G(v)^2} \), where \(d_G(u)\) denotes the degree of the ...
