Abstract

The first and the second Zagreb indices are two of the most thoroughly studied and oldest topological indices. Recently in 2013, Ranjini et al. re-defined the Zagreb indices, i.e., the redefined first, second and third Zagreb indices of a graph G are defined as , and , respectively. In this research paper, we compute the redefined Zagreb indices of the Titania Nanotubes TiO2[m, n].

Keywords: Carbon nanotube, Degree of vertex, Molecular graphs, Nano structures, Redefined zagreb indices, Titania nanotubes, Topological indices, Zagreb indices.
