摘要
利用锥拉伸锥压缩不动点定理,研究了一类带积分边界的二阶常微分非局部问题正解的存在性,得到了至少一个正解存在的充分条件,同时给出了相应边值问题的积分核.
By using the fixed-point theorem in cones,the existence of positive solutions was studied for a type of second-order nonlinear ordinary differential equations with integral boundary conditions.The sufficient conditions were obtained for at least one positive solution.Moreover,the associated integral kernels for boundary value problems were given.
