| Abstract: | .Letm(G,k)be the k-matching of graph G andz(G)being the Hosoya index of the graph G,is the total number ofm(G,k).The Hosoya index is the most important topological index of chemical graph theory.We shall investigate the Hosoya index of unicyclic graphs and get the first eighth smallest unicyclic graphs with respect to the Hosoya index. |

| Keywords: | Hosoya index matching unicyclic graph |
