摘要
研究了一类高阶奇异边值问题的正解.通过对问题进行适当的转化,然后利用μ0凹算子的不动点理论,得到了该奇异边值问题在非线性项满足一定条件时存在唯一正解的充分条件.
The positive solutions to a class of higher order singular boundary value problems are studied.By a proper transformation of this problem,the sufficient condition for the existence and uniqueness of positive solution to this class of singular boundary value problems was gained by using the fixed point theorems for u0 concave operators in the case that the nonlinear term satisfies some conditions.
