势最大时的预解矩阵和散射矩阵

Resolvent and scattering matrix at the maximum of the potential

Ivana Alexandrova, Jean-Francois Bony, Thierry Ramond

摘要:

研究了具有短程势的半经典Schrodinger算子在能量为势的唯一非退化全局极大值时预解式的微局部结构.我们证明了它是一个半经典的傅里叶积分算子,量子化了与固定双曲点相关联的传入和传出的拉格朗日子流形。然后我们讨论了这一结果的两个应用程序来描述的谱函数的结构和散射矩阵的薛定谔算子在临界能量。

英文摘要:

We study the microlocal structure of the resolvent of the semi-classical Schrodinger operator with short range potential at an energy which is a unique non-degenerate global maximum of the potential. We prove that it is a semi-classical Fourier integral operator quantizing the incoming and outgoing Lagrangian submanifolds associated to the fixed hyperbolic point. We then discuss two applications of this result to describing the structure of the spectral function and the scattering matrix of the Schrodinger operator at the critical energy.
