摘要
利用Krasnoselsk ii锥拉伸与锥压缩不动点定理,研究了一类二阶四点边值问题的正解存在性问题,得到了其无穷多个正解存在性的充分条件,改进和推广文献[1]的相关结论.
The existence of multiple positive solutions for a kind of second-order four-point boundary value problem is investigated by using Krasnoslskii fixed point theorem of cone expansion-compression type, the results rehated of are improved and extended.
