This paper discusses the application of degree in other aspects of graph theory,such as cycle,Hamiltonian graph and matching on the base of reference.

In this paper,we will research the domination number of hamiltonian graphs and prove that for a hamiltonian graph G of order n with minimun degree at least five,the domination munber of is at most 5n/14.

Then Tournament D *=(V,E) is Hamiltonian graph.
