摘要 利用上下解方法研究了一类四阶奇异边值问题正解的全局结构.证明了解集存在无界连通分支并给出了多个正解的存在性结果,推广和改进了相关文献的结果. The structure of the solution set for a class of fourth order singular boundary value problem is investigated. Behaviour of the solution set and the existence of multiple positive solutions are obtained by means of the method of upper and lower solutions.
