The connective eccentricity index of graphs and its applications to octane isomers and benzenoid hydrocarbons

Guangfu Wang, Lixia Yan, Shahid Zaman, Minjie Zhang

International Journal of Quantum Chemistry > 120 > 18 > n/a - n/a

The connective eccentricity index (CEI) of a graph G is defined as

ξ^{ee} (G) = \sum_{xy \in E_{G}} (\frac{1}{ε_{G} (x)} + \frac{1}{ε_{G} (y)})

, where ε_G(.) denotes the eccentricity of the corresponding vertex. The CEI obligates an influential ability, which is due to its estimating pharmaceutical properties. In this paper, we first characterize the extremal graphs with respect to the CEI among k‐connected graphs (k‐connected bipartite graphs) with a given...
