我们考虑在量子散射理论中,根据相对于原点对称的任意空间区域的逗留时间定义的对称时间延迟。对于在无穷远处衰减速度大于|x|−4的势,我们证明了对称时滞的存在性,并证明了它满足Lavine公式的各向异性版本。本研究揭示了各向异性膨胀型算子的重要性。
We consider, in quantum scattering theory, symmetrised time delay defined in terms of sojourn times in arbitrary spatial regions symmetric with respect to the origin. For potentials decaying more rapidly than |x|− 4at infinity, we show the existence of symmetrised time delay, and prove that it satisfies an anisotropic version of Lavine’s formula. The importance of an anisotropic dilations-type operator is revealed in our study.
