摘要
利用锥上的不动点定理给出了四阶微分方程奇异边值问题C2[0,1]正解存在的充分必要条件,推广了韦忠礼(2005,1999)的结果.
In this paper, the existence of positive solutions to singular boundary value problems of fourth order differential equations is considered. A necessary and sufficient condition for the existence of C^2[-0,1] positive solutions is given by means of the fixed point theorems on cones.
