F-Polynomial and Fourth Zagreb Polynomial of a Molecular Graph

N. K. Raut

Abstract: Let G = (V, E) be molecular graphs. The set of vertex and edge are denoted by V= V (G) and E= E (G) respectively. F-index and fourth Zagreb index can be found from respective polynomials of F-polynomial and fourth Zagreb polynomial. In this paper F-polynomial and fourth Zagreb polynomial of 7-phenacene are studied

Keywords: F-index, F-polynomial, fourth Zagreb polynomial, fourth Zagreb index, eccentricity
