摘要 综合利用Leray-Schauder度理论的同伦不变性、上下解方法等,在符号型Nagumo条件下获得了一类三阶非线性常微分方程在非线性边界条件下解的存在性结果. By using Leray-Schauder degree theory and the method of Upper and Lower solutions, the existence result is established for a class of nonlinear third-order two-point boundary value problems under Sign-Type Nagumo condition.
