Transmission and reciprocal transmission topological indices and co-indices of Indu-Bala products of graphs

Abstract

The transmission of a vertex u in a connected graph G is denoted by s(?) and defined by [Formula presented]; that is, the sum of the distances between u and all other vertices of a graph G. The reciprocal transmission of a vertex u in a connected graph G is denoted by rs(u) and defined by [Formula presented]; that is, the sum of the reciprocal of distances between u and all other vertices of a graph G. In this paper we obtain explicit formulae for various transmission and reciprocal transmission based topological indices and co-indices of Indu-Bala product of graphs.
