摘要
运用锥拉压定理,研究了三阶非线性边值问题耦合系统.一些确保该三阶边值问题耦合系统至少有一个正解的充分条件被得到,并给出一些例子来验证我们的结论.
By using cone expansion-compression theorem in this paper,we study boundary value problems for systems of nonlinear third-order differential equation.Some sufficient conditions are obtained which guarantee the boundary value problems for systems of nonlinear third-order differential equation have at least one positive solu- tion.Some examples are given to verify our results.
