	Article:	FORTH ATOM-BOND CONNECTIVITY INDEX OF SOME FAMOUS NANOTUBES. Authors: .


	Abstract: Let G=(V,E) be a simple connected graph. The sets of vertices and edges of G are denoted by V=V(G) and E=E(G), respectively. In such a simple molecular graph, vertices represent atoms and edges represent bonds. The goal of this paper is to compute the ABC₄ index for some nanotubes designed by Diudea. Keywords: Molecular graph, Atom-bond connectivity index, ABC₄ index.
