在这项工作中,我们的目的是对文献[1]中一个半经典薛定谔方程的解所表现出的色散效应给出一些定量的见解。我们定量地描述了在这种非紧几何中能量在长时间半经典极限中的局域化,并给出了能量在紧集上保持局域化的条件。我们还解释了我们的结果如何可以用一种直接的方式来描述对平滑类型估计的有效性的障碍。
Our aim in this work is to give some quantitative insight on the dispersive effects exhibited by solutions of a semiclassical Schrödinger-type equation in. We describe quantitatively the localisation of the energy in a long-time semiclassical limit within this non compact geometry and exhibit conditions under which the energy remains localized on compact sets. We also explain how our results can be applied in a straightforward way to describe obstructions to the validity of smoothing type estimates.
