非定域薛定谔算符的短程势和长程势之间的阈值

Threshold between short and long-range potentials for non-local Schrödinger operators

Atsuhide Ishida, Kazuyuki Wada

摘要:

我们发展散射理论的非本地薛定谔算子定义的拉普拉斯函数,包括其分数功率$(-Δ)^ρ$与$0<ρ\leqslant1$。特别是,我们的功能属于一个更广泛的类比一组伯恩斯坦功能。通过证明波算符的存在性和不存在性,我们澄清了微扰势的短程和长程衰变条件之间的阈值。

英文摘要:

We develop scattering theory for non-local Schrödinger operators defined by functions of the Laplacian that include its fractional power $(-Δ)^ρ$ with $0<ρ\leqslant1$. In particular, our function belongs to a wider class than the set of Bernstein functions. By showing the existence and non-existence of the wave operators, we clarify the threshold between the short and long-range decay conditions for perturbational potentials.
