摘要: 讨论了一个抛物型偏微分方程动态边值的初值控制问题. 在一定条件下得出了上下解的有序性, 并由此引入迭代序列讨论了整体解的存在性以及计算办法, 并给出了问题具有无穷多解的算例.

Abstract: An initial control problem with dynamic boundary conditions is investigated by using a method of maximal principle. The comparison principle and existence of solutions for the control problem under some assumptions are proved. Some examples with multiple solutions and unique solution are gived.

Key words: boundary value problem;upper-lower solutions, control problem, maximal principle, nonlocal, parabolic equation
