Abstract
The concept of hyper Zagreb index, Zagreb and M-polynomials are establish in chemical graph theory based on the degree of the vertex. It is reported that these indices are useful in the study of anti-inflammatory activities of certain chemical networks. In this paper, we determine hyper Zagreb index, Zagreb and Mpolynomials for an infinite class of Titania nanotubes TiO2 [m, n].
Keywords: Hyper Zagreb index, Zagreb polynomials, M-polynomial, TiO2 nanotubes.
