| Abstract: | The geometric property of solution for the nonlinear system playes an important role in both theory and application.By using the reflective function theory,we discuss the necessary and sufficient conditions for the existence of reflective functions satisfying the special relation of nonlinear system.By applying the results we study the geometric property of the periodic solution for the periodic nonlinear system,and set up the decision theorems of the existence of the periodic solution and stability for the nonlinear system.All these results provide some new theoretical basis and criteria for explaining the complicated law of motion of objects. |
