Opis:: Let G be a simple connected graph with the vertex set V = V(G) and the edge set E = E(G),without loops and multiple edges. For counting qoc strips in G, Diudea introduced the Ω-polynomial of G and was defined as Ω(G, x) = Σ^k _{i=1_{X ^c, where C_{1₁, C₂..., C_k be the “opposite edge strips” ops of G and c_i = |C_i| (I = 1, 2,..., k). One can obtain the Sd-polynomial by replacing x^c with x^E(G)-c in Ω-polynomial. Then the Sd-index will be the first derivative of Sd(x) evaluated at x = 1. In this paper we compute the Sd-polynomial and Sd-index of an infinite class of “Armchair Polyhex Nanotubes”.}}}

m-connectivety index
m-sum connectivity index
Opis:: The m-connectivety and m-sum connectivity indices of G are defined as to be [wzór] and [wzór] where [wzór] runs over all paths of length m in G and di is the degree of vertex νi. In this paper, we give explicit formulas for the second-connectivity and second-sum-connectivity indices of an infinite class of Armchair Polyhex Nanotubes TUAC6[m,n].

Opis:: Let G be a simple connected graph with the vertex set V = V(G) and the edge set E = E(G), without loops and multiple edges. For counting qoc strips in G, Omega polynomial was introduced by Diudea and was defined as Ω(G,x ) = [wzór] where m(G,c) be the number of qoc strips of length c in the graph G. Following Omega polynomial, the Sadhana polynomial was defined by Ashrafi et al as Sd(G,x) = [wzór]. In this paper we compute the Pi polynomial Π(G,x) =[wzór] and Pi index Π(G ) = [wzór] of an infinite class of “Armchair Polyhex Nanotubes TUAC ₆ [m,n]”.
