Computing some connectivity indices of TUHRC4(S) and TUSC4C8(S) Nanotubes

Mohammad Reza Farahani


Let G be a simple connected graph in chemical graph theory and e=uv be an edge of G. Atom-Bond Connectivity index, Randic connectivity index, geometric-arithmetic index and sum-connectivity index of G are defined as    and  respectively. In this paper we compute ABC(G), χ(G), GA(G) and X(G) indices of  G1=TUHRC4(S)  and G2=TUSC4C8(S) Nanotubes.
