摘要
利用变形边界函数法与上下解方法,研究了一类具非线性边界条件的半线性时滞微分方程边值问题,得到了此边值问题解的存在性的充分条件.
A boundary value problem for semi-linear retarded differential equations with nonlinear boundary condition is studied. By using of modifying the boundary functions and a new method to construct upper solution and lower solution, sufficient conditions for the existence of the problems＇ solution axe established.
