Harmonic indices of polyhex zigzag TUZC6[m;n] nanotube and nanotori

The first and fifth Harmonic indices for simple connected molecular graph G have been introduced as H-1(G) = Sigma(uv is an element of(G)) 2/d(u)+d(v) and H-5(G) = Sigma(uv is an element of E(G)) 2/S-u+S-v, where S-u := Sigma(v is an element of N(u)) d(v). The aim of this paper is computing the Harmonic indices for polyhex zigzag TUZC(6)[m,n] Nanotube and Nanotori. We calculate the first and the fifth harmonic indices for planar polyhex zigzag nanotube PTUZC(6)[m,n] and polyhex zigzag nanotube TUZC(6)[m,n].
