一类慢衰减势函数预解式的零能渐近性

Zero energy asymptotics of the resolvent for a class of slowly decaying potentials

S. Fournais, E. Skibsted

摘要:

我们证明了具有长程势的两体薛定谔算子在无穷远处具有正维里的零能极限吸收原理。更确切地说,我们建立了一个完整的渐近展开的加权空间中的预解式时,谱参数变化的锥,两个分支的边界的锥被给定的正实轴。主要工具是特征值零点不存在、奇异摄动理论和微局部估计。

英文摘要:

We prove a limiting absorption principle at zero energy for two-body Schrödinger operators with long-range potentials having a positive virial at infinity. More precisely, we establish a complete asymptotic expansion of the resolvent in weighted spaces when the spectral parameter varies in cones; one of the two branches of boundary for the cones being given by the positive real axis. The principal tools are absence of eigenvalue at zero, singular Mourre theory and microlocal estimates.
