Zagreb Polynomials and redefined Zagreb indices of line graph of HAC5C6C7[p,q] Nanotube

Abstract

The application of graph theory in chemical and molecular structure research far exceeds people’s expectations, and it has recently grown exponentially. In the molecular graph, atoms are represented by vertices and bonded by edges. In this report, we study the Zagreb-polynomials of line graph of HAC5C6C7[p, q] and compute some degree-based topological indices from it.
