A Comparison of the Schultz Molecular Topological Index with the Wiener Index
The Schultz molecular topological index (MTI) is compared with the Wiener index (W) of a molecular graph. It is shown that 2vminW < MTI ≤ 4vmaxW holds for any (connected) graph Γ, with vmin and vmax denoting the smallest and the largest valency, respectively, of the vertices of Γ. For …
