Graovac-Ghorbani index is a new version of the atom-bond connectivity index. D. Pacheco et al. Rui Song et al. [1] determine the maximal Graovac-Ghorbani index of bicyclic graphs. Motivated by their nice work, in this paper we determined the maximal Graovac-Ghorbani index of a class of tricyclic graphs and characterize the corresponding extremal graphs.

摘要

Graovac-Ghorbani index is a new version of the atom-bond connectivity index. D. Pacheco et al. Rui Song et al. [1] determine the maximal Graovac-Ghorbani index of bicyclic graphs. Motivated by their nice work, in this paper we determined the maximal Graovac-Ghorbani index of a class of tricyclic graphs and characterize the corresponding extremal graphs.
