| 概要 | We consider Schr dinger equations in with
electro-magnetic potentials. The potentials belong to
, and typically they are time-independent or
determined as solutions to inhomogeneous wave equations.
We prove Kato type smoothing estimates for solutions. We
also apply this result to the Maxwell-Schr dinger
equations in the Lorentz gauge and prove unique
solvability of this system in the energy space. |
