论文摘要
在这项工作中,我们表明时空一阶系统最小二乘(FOSLS)公式[Führer,Karkulik,Comput。数学。应用。 92(2021)]用于热方程式及其最近的概括[Gantner,Stevenson,Esaim Math。模型。 numer。肛门。 55(2021)]到任意的二阶PDES可以用来有效地解决参数依赖性问题,最佳控制问题以及时间依赖性空间域的问题。
In this work, we show that the space-time first-order system least-squares (FOSLS) formulation [Führer, Karkulik, Comput. Math. Appl. 92 (2021)] for the heat equation and its recent generalization [Gantner, Stevenson, ESAIM Math. Model. Numer. Anal. 55 (2021)] to arbitrary second-order parabolic PDEs can be used to efficiently solve parameter-dependent problems, optimal control problems, and problems on time-dependent spatial domains.
