## Abstract

Topological indices are real numbers that are presented as graph parame- ters introduced during studies conducted on the molecular graphs in chemistry and can describe some physical and chemical properties of molecules. In this paper we compute eccentricity based topological indices for crown graph, gear graph, friendship graph, helm graph flower graph and their line graphs.

## Keywords
