A Note on Connectivity and λModified Wiener Index

Wei Gao, Yun Gao

Abstract

In theoretical chemistry, λmodified Wiener index is a graph invariant topological index to analyze the chemical properties of molecular structure. In this note, we determine the minimum λmodified Wiener index of graph with fixed connectivity or edge- connectivity. Our results also present the sufficient and necessary condition for reaching the lower bound.
