Abstract

In the present investigation, we compute the value of eccentric topological indices on the basis of edges of annihilating - ideal graphs namely, the first zagreb eccentricity index, third zagreb eccentricity index, geometric - arithmetic eccentricity index, atom-bond connectivity eccentricity index and the fourth type of eccentric harmonic index. In addition, we propose an open question in this paper.

Keywords and Phrases

Annihilating - ideal graph, eccentricity, topological index.
