Amal Alphonse, Michael Hintermüller, Carlos N. Rautenberg

摘要:

本文研究了障碍型椭圆型拟变分不等式,证明了这类拟变分不等式解的存在性、方向可微性和最优控制的一些结果.我们给出了三个存在性定理的基础上的顺序方法,迭代计划和序列正则化通过偏微分方程。我们表明,解决方案映射到一组解决方案的QVI的源项是定向可微的一般数据和局部Hadamard可微障碍映射,从而特别是我们以前的工作,提供了第一个可微性结果QVI在无限维的结果。QVI约束的最优控制问题也被认为是我们得到的各种形式的平稳性条件的控制问题,从而提供在这方面的第一个这样的结果。

英文摘要:

We focus on elliptic quasi-variational inequalities (QVIs) of obstacle type and prove a number of results on the existence of solutions, directional differentiability and optimal control of such QVIs. We give three existence theorems based on an order approach, an iteration scheme and a sequential regularisation through partial differential equations. We show that the solution map taking the source term into the set of solutions of the QVI is directionally differentiable for general data and locally Hadamard differentiable obstacle mappings, thereby extending in particular the results of our previous work which provided the first differentiability result for QVIs in infinite dimensions. Optimal control problems with QVI constraints are also considered and we derive various forms of stationarity conditions for control problems, thus supplying among the first such results in this area.
