【摘要】 利用锥上的Krasnoselskii不动点定理研究了一类具有积分边界条件的四阶非局部微分方程组边值问题正解的存在性。通过在Banach空间定义一个全连续的算子,得到了它至少存在1个正解的充分条件。更多还原

【Abstract】 By using Krasnoselskii fixed point theorem in a cone,the existence of positive solutions for nonlocal forth order boundary value problem systems with integral boundary conditions is studied.By defining a completely continuous operator in a Banach space,the sufficient condition under which the above problem has at least one positive solution is derived.更多还原
