On the Schr\"odinger equations with time-dependent potentials growing polynomially in the spatial direction

The Cauchy problem for the Schr"odinger equations is studied with time-dependent potentials growing polynomially in the spatial direction. First the existence and the uniqueness of solutions are shown in the weighted Sobolev spaces. In addition, we suppose that our potentials are depending on a parameter. Secondly it is shown that if potentials depend continuously and differentiably on the parameter, the solutions to the Schr"odinger equations respectively become continuous and differentiable with respect to its parameter.
