摘　　要：利用锥上不动点定理.研究了一类含积分边界条件的三阶微分方程正解的存在性,并给出了至少一个正解和两个正解存在的充分条件,同时还讨论了正解不存在的充分条件.By using the fixed point theorem in a cone,the existence and multiplicity of positive solutions for a class of third-order ordinary differential equations with integral boundary conditions were investigated.The sufficient conditions for existence of at least one or two positive solutions were obtained.Meanwhile,the nonexistence of positive solution was also studied.
