In this paper, based on a new system of three Riccati equations, we give a new method to construct more new exact solutions of nonlinear differential equations
With a perfect mathematical method by us, we obtain some expressions of the orbital effect for a test particle and some meaningful results in the gravitational
By means of a special Painlevé-Backlund transformation and a multilinear variable separation approach,an exact solution with arbitrary functions of the (2+
