Abstract

A topological index has a vital role in molecular chemistry. There are various topological descriptors in theoretical chemistry in particular; degree- based topological indices, distance-based, eccentricity- based and counting related indices of graphs. In this paper, we have obtained analytical expressions for various variants of eccentricity based indices such as first and second multiplicative Zagreb eccentricity indices, total eccentric index, connective eccentric index, Ediz eccentric connectivity index, modified and augmented eccentric connectivity indices and their respective polynomials of polygonal cylinder.
