关于二阶非线性常微分方程周期边值问题的注记

Remarks on the Periodic Boundary Value Problems for Nonlinear Second Order Ordinary Differential Equations

Faouzi Haddouchi, Slimane Benaicha

摘要:

研究了二阶周期边值问题的上下解$α$和$β$分别违反边界条件$ α(0)=α(2π)$和$β(0)=β(2π)$时解的存在性和单调方法.我们提出了几个比较结果。我们证明了上下解方法与单调迭代技巧相结合是获得解存在性构造性证明的有效方法。

英文摘要:

This paper is devoted to study the existence of solutions and the monotone method of second-order periodic boundary value problems when the lower and upper solutions $α$ and $β$ violate the boundary conditions $ α(0)=α(2π)$ and $β(0)=β(2π)$. We present several comparison results. We show that the method of lower and upper solutions coupled with the monotone iterative technique is valid to obtain constuctive proof of existence of solutions.
