摘要
研究了反序上下解条件下三阶微分方程三点边值问题解的存在性与唯一性.利用单调迭代方法,分别得到解存在与唯一的充分条件,在满足解的唯一性的条件下,给出了求解的迭代序列及误差估计式.
The existence and uniqueness of solutions of third-order three-points boundary value problems with lower and upper solutions were studied. The sufficient conditions for the existence and uniqueness of solutions were provided by use of the monotone iterative method in the reversed order. The iterative sequence for solving a solution and its error estimate formula under the condition of unique solution were presented.
