摘要
根据锥上不动点指数理论,研究了微分方程组正周期解的存在性。应用线性问题的第一特征值和拓扑度理论建立了其正解的存在性定理。
By using the fixed-point index theory,we study the problem of nonlinear ordinary differential systems with periodic boundary value.The existence theoem on positive solution is established by using the first eigenvalue of the correspondind linear problems and theorem for product of topology degree.
