FIRST AND SECOND ZAGREB INDICES AND POLYNOMIALS OF V-PHENYLENIC NANOTUBES AND NANOTORI
AbstractLet G be a simple molecular graph with vertex and edge sets V(G) and E(G), respectively. In 1972, Gutman and Trinajstić introduced the First and Second Zagreb topological indices of molecular graphs. These topological indices are useful in the study of anti-inflammatory activities of certain chemical instances, and in elsewhere. In this present study, compute the First Zagreb index Zg1(G)= and Second Zagreb index Zg2(G)=
and the First Zagreb polynomial Zg1(G,x)=
and the Second Zagreb polynomial Zg2(G,x)=
of V-Phenylenic Nanotubes and Nanotori.
