考虑了具有快速振荡势的薛定谔算子。这样的势相对于自由薛定谔算符-Δ来说并不是相对紧的。我们证明了振荡势V不改变−Δ的本征谱。此外,我们得到的负特征值和的上界。
Schrödinger operatorswith rapidly oscillating potentialsVsuch asare considered. Such potentials are not relatively compact with respect to the free Schrödinger operator −Δ. We show that the oscillating potentialVdo not change the essential spectrum of −Δ. Moreover we derive upper bounds for negative eigenvalue sums ofĤ.
