收藏 引用
Journal of Mathematical Research and Exposition 2008年 第3期28卷 720-726页
作者: LI Zhi-long School of Informational Management Jiangxi University of Finance and Economics Jiangxi 330013 China
In this paper, we study the nonlinear second-order boundary value problem of delay differential equation.. Without the assumption of the nonnegativity of f, we still obtain the existence of the positive solution.
