| Abstract: | With the aid of homogeneous balance principle and a nonlinear subsidiary ordinary differential equation(sub-ODE),the exact solutions to the generalized fifth order KdV equations with arbitrary positive power nonlinearities are found out.The solutions are expressed by the bell type solitary wave solutions,the kink type solitary wave solutions and the trigonometric functional periodic solutions.Exact solutions obtained by other methods with the previous unanimous,and includes some of the previous literature d... |
