✦ Synopsis


Let us reflect an n-dimensional cube in all its faces. The 2n + 1 cubes obtained form a so-called n-dimensional cross. KBrteszi [l] raised the question whether it is possible to construct a tiling of the n-dimensional space dimensional crosses.

We say that this such a tiling is regular if neighbouring entire (n -1)-dimensional faces of the original cubes.

Kkteszi's question is partially answered by the following

On the Regularity of an Obstacle Control
✍ Hongwei Lou 📂 Article 📅 2001 🏛 Elsevier Science 🌐 English ⚖ 145 KB

An optimal control problem of the obstacle for an elliptic variational inequality is considered, in which the obstacle is regarded as the control. To get the regularity of the optimal pair, a new related control problem is introduced. By proving the existence of an optimal pair to such a new control
