我们得到了具有长程势的薛定谔算子谱函数的半经典渐近性。我们研究了非囚禁能级的情况,也研究了岛内势垒的情况,其中由于囚禁轨迹出现了共振。
We obtain semiclassical asymptotics for the spectral function of Schrödinger operators with long-range potentials. We study the case of non-trapping energy levels and also the case of a potential well inside an island, where resonances due to trapped trajectories appear.
