| Outline of Final Research Achievements |
By using the representation of solutions to Schroedinger equations in terms of wave packet transform given by the representative of this research project and the co-workers, the representative and the co-workers has studied properties of solutions to Schroedinger equations. More precisely, we have characterize singularities to Schroedinger equations with time dependent sub-quadratic potentials and for purturbed harmonic oscillator in terms of information of
initial data.
We have studied existence and completeness of wave operators for Schroedinger equations with time dependent potentials. We have shown existence and completeness of wave operator for Schroedinger equations with time dependent shortrange potentials.
