摘要
利用锥压缩锥拉伸不动点定理及一些分析技巧,建立一类四阶非线性微分方程的积分边值问题存在一个及多个正解的充分条件,推广和改进ZHANG Xue-mei等人的研究结果.
By employing the cone compression and the extension fixed point theorem and some analytical skills, we establish the sufficient conditions for the existence of one and multiple positive solutions for nonlinear boundary-value problems of fourth-order differential equations with integral boundary conditions, our results generalize and improve ZHANG Xuemei et al's results.
