Szeged and vertex PI index of graphs over modules
Summary: If we have a commutative ring \(R\) and it is identified as \(1\neq 0\) there is an \(R\)-module \(M\), \(G_R(M)\) will denote the Scalar product graph of \(M\). Vertices of \(G_R(M)\) are elements of \(M\), and \(a\), \(b\) in \(M\) are adjoining if \(a = rb\) or \(b = ra\) for some \(r\in R\).Nouri Jouybari, Mostafa +1 more

Computing Vertex PI Index of Tetrathiafulvalene Dendrimers
2010General formulas are obtained for the vertex Padmakar-Ivan index (PIv) of tetrathiafulvalene (TTF) dendrimer, whereby TTF units we are employed as branching centers. The PIv index is a Wiener-Szeged-like index developed very recently. This topological index is defined as the summation of all sums of nu(e) and nv(e), over all edges of connected graph G.
