%0 Journal Article %T The largest $n-1$ Hosoya indices of unicyclic graphs %A Guihai Yu %A Lihua Feng %A Aleksandar Ilic %J Mathematics %D 2011 %I arXiv %X The Hosoya index $Z (G)$ of a graph $G$ is defined as the total number of edge independent sets of $G$. In this paper, we extend the research of [J. Ou, On extremal unicyclic molecular graphs with maximal Hosoya index, \textit{Discrete Appl. Math.} 157 (2009) 391--397.] and [Y. Ye, X. Pan, H. Liu, Ordering unicyclic graphs with respect to Hosoya indices and Merrifield-Simmons indices, \textit{MATCH Commun. Math. Comput. Chem.} 59 (2008) 191--202.] and order the largest $n-1$ unicyclic graphs with respect to the Hosoya index. %U http://arxiv.org/abs/1105.5522v1
