• ON ECCENTRIC CONNECTIVITY INDEX OF......

U. MARY*, S. SHAMILA

Abstract


The eccentric connectivity index based on degree and eccentricity of the vertices of a graph is a widely used graph invariant in mathematics. In this paper we present the explicit generalized expression for the eccentric connectivity index of the subdivision graph of some special graphs such as Friendship graph, Star graph, Dipole graph and their line graphs.


Keywords


Dipole graph, Eccentric connectivity index, Friendship graph, Star graph, Subdivision graph.
