Topological indices of the subdivision graphs of the nanostructure TUC₄C₈(R) using M-polynomials

Abstract

Topological indices of chemical structures are found to be very useful in understanding many of their intrinsic properties. Wiener index, Zagreb indices, the generalized Randić index, Szeged index and harmonic index are some of the indices commonly used for the QSAR and QSPR of chemical graphs and nanostructures. In this article, we compute some of the important topological indices of the 2D-lattice, nanotube and nanotorus of the TUC₄C₈(R) [p, q] nanostructure and their subdivision graphs by finding their M-polynomials.
