摘要
通过利用单调迭代技巧,上下解方法及最大值原理讨论了一类2n阶奇异边值问题,得到了C(2n-1)[0,1]正解存在的充分必要条件及C(2n-2)[0,1]正解存在的充分条件.
A necessary and sufficient condition for the existence of C^(2n-1)[0,1] positive solutions to the singular boundary has been obtained by using the monotone iterative techniques. By constructing lower and upper solutions and with the maximal theorem, a sufficient condition for the existence of C^(2n-2)[0,1] positive solutions is also given.
