Topological Indices Based on the Line Graph of the Molecular Graph

The topological index ε recently proposed by one of the authors [E. Estrada, J . Chem . Inf . Comput . Sci . 1995, 35, 31−33] is shown to be identical to the connectivity index of the line graph of the molecular graph. This observation makes it possible to conceive a whole class of novel, line-graph... View More
