摘要:

我们考虑的Neumann实现的磁拉普拉斯算子在$\mathbb{R}^3_+$,在这种情况下,磁场具有分段恒定的强度和一个统一的方向。该算子有望成为研究三维超导体在不连续磁场作用下的正常态阈值的有效模型。我们回顾了最近的一些结果上面的下确界的频谱上述运营商。

英文摘要:

We consider the Neumann realization of the magnetic laplacian in $\mathbb{R}^3_+$, in the case in which the magnetic field has a piecewise constant strength and a uniform direction. This operator is expected to be an effective model in studying the threshold to the normal state for a 3D superconductor exposed to a discontinuous magnetic field. We review some recent results above the infimum of the spectrum of the aforementioned operator.
