| Abstract: | A tree is called r-leaves tree if it contains r endvertices.In this paper,it is studied that the Hosoya index value of r-leave and 5-leave tree of order n,and characterize the 5-leave tree with maximal and minimal Hosoya index value,and the 4-leave tree with minimal Hosoya index value. |
