Keywords: edge revised Szeged index; edge Szeged index; edge topological property; fullerene; PI index; Introduction Throughout this paper the term "graph" refers to a finite and simple graph. The set of vertices and edges of a graph G are denoted by V(G) and E(G), respectively

• graph. In this work, the topological properties of a class of fullerenes were given by edge contributions of its molecular graph. Our calculations with this and other classes of fullerenes suggest that the edge PI index can be computed by a polynomial of degree 2, whereas edge Szeged and edge revised
