摘要: 用共轭方程的Carleman估计研究退化抛物方程的边界控制问题, 得到了该问题的近似可控性. 结果表明: 对任意一个目标函数, 均存在一个控制函数, 使问题的解在有限时间内可以充分接近目标函数.

关键词: 退化抛物方程, 边界控制, 近似可控性, 唯一延拓性

Abstract: By using Carleman estimates of the adjoint equations, we investigated the boundary control problem of degenerate parabolic equations, and obtained its approximate controllability. The result shows that for any objective function, there exists a control function such that the solution of the problem can be fully close to the objective function in a finite time.

Key words: degenerate parabolic equation, boundary control, approximate controllability,  , unique continuity
