我们确定了Rn上某些薛定谔方程解的奇点在时间上的行为。我们假设哈密顿量的形式H 0 +V,其中,和其中V是有界的和光滑的衰减导数。当所有ωk=0时,exp(−itH)的核k(t,x,y)在x中是光滑的,对于每个固定的(t,y)。当所有的ω 1都相等但不为零时,初始奇点在时间和位置x =(−1)my“重建”,就像ifV=0;否则是正则的。在一般情况下,当ωjt/π=ljforj=j1,...,Jr.
We determine the behavior in time of singularities of solutions to some Schrödinger equations onRn. We assume the Hamiltonians are of the formH0+V, where, and whereVis bounded and smooth with decaying derivatives. When all ωk=0, the kernelk(t,x,y) of exp (−itH) is smooth inxfor every fixed (t,y). When all ω1are equal but non-zero, the initial singularity “reconstructs” at timesand positionsx=(−1)my, just as ifV=0;kis otherwise regular. In the general case, the singular support is shown to be contained in the union of the hyperplanes, when ωjt/π=ljforj=j1,...,jr.
