Calculating Degree Based Topological Indices of Line Graph of HAC5C6C7[p,q] Nanotube via M-Polynomial

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 M-polynomial of line graph ofHAC5C6C7[p, q] and recover many degree-based topological indices from it.
