关于变磁场下半经典三维Neumann Laplacian

On the semi-classical 3D Neumann Laplacian with variable magnetic field

Nicolas Raymond

摘要:

在本文中,我们感兴趣的是在3维的Neumann-Laplacian谱的半经典估计。这项工作的目的是提出一个补充的情况下,在恒定磁场的情况下,Helffer和Morame的文件中提出的。更确切地说,在这种情况下,当磁场是可变的,并在最一般的条件下,可以观察到的边界本地化,我们证明了一个三项上限的最低本征值,并建立一些半经典行为的频谱。

英文摘要:

In this paper we are interested in the semi-classical estimates of the spectrum of the Neumann Laplacian in dimension 3. This work aims to present a complementary case to the one presented in the paper of Helffer and Morame in the case of constant magnetic field. More precisely, in the case when the magnetic field is variable and under the most generic condition for which boundary localizations can be observed, we prove a three terms upper bound for the lowest eigenvalue and establish some semi-classical behaviour of the spectrum.
