摘要

本文讨论了二维振荡域上包含单向振荡系数的广义平稳Stokes方程的分布最优控制问题(OCP)的均匀化问题。所考虑的代价泛函是包含单向振荡系数矩阵的狄利克雷型。利用展开算子对最优控制进行了刻画，并研究了该OCP的均匀化问题。由于控制Stokes方程和代价泛函中都存在振荡矩阵，在收敛分析中得到了涉及摄动张量的极限OCP。

Homogenization of distributive optimal control problem governed by Stokes system in an oscillating domain

The present article deals with the homogenization of a distributive optimal control problem (OCP) subjected to the more generalized stationary Stokes equation involving unidirectional oscillating coefficients posed in a two-dimensional oscillating domain. The cost functional considered is of the Dirichlet type involving a unidirectional oscillating coefficient matrix. We characterize the optimal control and study the homogenization of this OCP with the aid of the unfolding operator. Due to the presence of oscillating matrices both in the governing Stokes equations and the cost functional, one obtains the limit OCP involving a perturbed tensor in the convergence analysis.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
