• COMPUTING CERTAIN TOPOLOGICAL INDICES FOR LINE GRAPHS OF TADPOLE GRAPHS, WHEEL GRAPH AND LADDER GRAPH

Abstract

Topological indices have been used as a special tools in mathematical chemistry to predict physico-chemical properties of certain chemical compounds. Recently various new topological indices have been conceived by researchers such as Sanskruti index , fifth  and  Zagreb indices, fifth  and  multiplicative Zagreb indices. In this paper, we give explicit formulae for tadpole graph, wheel graph and ladder graph and their corresponding line graphs for the above mentioned topological indices in terms of the order of the original graph .
