The Wiener Index of Unicyclic Graphs with Girth and the Matching Number

Ya-Hong Chen, Xiao-Dong Zhang

Published 2011-02-26Version 1

In this paper, we investigate how the Wiener index of unicyclic graphs varies with graph operations. These results are used to present a sharp lower bound for the Wiener index of unicyclic graphs of order $n$ with girth and the matching number $\beta\ge \frac{3g}{2}$. Moreover, we characterize all extremal graphs which attain the lower bound.
