Abstract: The eccentricity of a vertex is the maximum distance from it to any other vertex, ec(u) = max{d(u, v)|?u?V(G)}. In this paper we compute total eccentricity index, average eccentricity index, different versions of eccentricity-based Zagreb indices(M1* (G), M1??(G), M2? (G)), fourth GA eccentricity index, fifth ABC eccentricity index, eccentric connectivity index and eccentric connectivity polynomial of line graphs of CNC3[2] and CNC4[2] carbon nanocones.

Keywords: Carbon nanocone, eccentricity, eccentric Zagreb index, line graph, topological index
