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.
