SHIGEHALLI V. S., SHANMUKH KUCHABAL*

Abstract


Let G be the connected graph. The Wiener index is the sum of all distances between vertices of G, whereas the hyper-Wiener index is defined as . In this paper we prove some general results on the topological indices of thorny-star graphs and some bounds on it.


Keywords


Molecular graphs, Wiener index and hyper-Wiener index.
