摘要 通过对一类三阶非线性半正边值问题的讨论,应用锥上的不动点定理,给出了一类三阶半正边值问题正解的存在性的充分条件并给出了证明. By investigating a class of third-order nonlinear semipositone boundary value problems, and applying a fixed point theorm in cones , the sufficient conditions for the existence of positive solutions to a class of third-order semipositone boundary value problems are put forth and the subsequent rigid validity proving process has proved them to true.
