Eccentric Connectivity Index and Polynomial of Some Graphs

A. R. Bindusree, V. Lokesha & P. S. Ranjini · Journal of Advances in Mathematics and Computer Science · 2015

Aims/ Objectives: Let G be a simple and connected graph with n vertices and m edges. The Eccentric connectivity index of G is defined as the summation of the product of degree and eccentricity of the vertices [1]. Eccentric connectivity polynomial is a topological polynomial of G...
