Existence of Positive Periodic Solutions for the Second Order and Fourth Order Nonlinear Ordinary Differential System

摘要：

In this paper, by using the fixed-point index theory and product of topology degree theory, the existence results on positive solutions is established to the second order and fourth order nonlinear ordinary differential system with periodic boundary value. Our result is essential and do not require the nonlinear terms are superlinear or sublinear at ends(zero or infinry) and the system must have the same order.
