| Abstract: | This paper investigated the properties of the Wiener index of unicyclic graphs, which are used to give a lower bound for the Wiener index of unicylic graphs of order 2β having perfect matching.Moreover,all extremal unicyclic graphs which attain the lower bound were characterized. |
| Keywords: | Wiener index perfect matching unicyclic graph tree |
