摘要: It is found that there exists necessary and sufficient conditions for the existence of at least one periodic solution a type parametric second-order ordinary differential equations, known as Mathieu-Duffing equation. The correctness have been pointed out by Schauder's fixed point theorem, validity assumptions has shown analysis an illustrative example in non-linear vibration.
