摘要:

本文考虑带Dirichlet边界条件的二维有界域上的质量临界聚焦型非线性薛定谔方程。在无控制时,已知从足够大的初始数据出发的自由解会发生爆破;更准确地说,给定有限个点,存在在爆破时刻恰好于这些点处爆破的特定轮廓。对于这些轮廓的扰动,我们证明:借助位于包含爆破点的开集内的适当非线性反馈律,可阻止爆破发生;具体而言,我们构造了在爆破时刻前起作用的短时控制,使解能延拓至全局时间。这是首个关于非线性薛定谔型方程爆破轮廓控制的结果。进一步假设控制支撑满足几何控制条件,我们能证明此类爆破轮廓的零能控性结果。最后,我们讨论了向三维域推广的可能性。

英文摘要:

In this paper, we consider the mass-critical focusing nonlinear Schrödinger on bounded two-dimensional domains with Dirichlet boundary conditions. In the absence of control, it is well-known that free solutions starting from initial data sufficiently large can blow-up. More precisely, given a finite number of points, there exists particular profiles blowing up exactly at these points at the blow-up time. For pertubations of these profiles, we show that, with the help of an appropriate nonlinear feedback law located in an open set containing the blow-up points, the blow-up can be prevented from happening. More specifically, we construct a small-time control acting just before the blow-up time. The solution may then be extended globally in time. This is the first result of control for blow-up profiles for nonlinear Schrödinger type equations. Assuming further a geometrical control condition on the support of the control, we are able to prove a null-controllability result for such blow-up profiles. Finally, we discuss possible extensions to three-dimensional domains.
