Geometric arithmetic and mostar indices of P 2n + F Pn +1

Abstract

Let G = (V, E) be a simple connected graph, where V(G) and E(G) represent the vertex set and edge set of G respectively. The vertex set V(G) associates with the atoms and the edge set E(G) associates with the bonds of the atoms in a chemical graph. For a connected graph G, the second geometric-arithmetic index GAv (G) index is denoted as , and the Mostar M (G) index of a graph G is formulated by , where nu (e) is the number of vertices which are closer to the vertex u than to vertex v of e and nv (e) is the number of vertices which are closer to vertex v than to the vertex u of e. The aim of this paper is to calculate and compare the geometric-arithmetic GAv (G) index and Mostar Mo (G) index of P 2n + FPn +1.
