Remark on Estimates in Modulation Spaces for Schrödinger Evolution Operators with Sub-quadratic Potentials
Kosuzu Hamaoka, Keiichi Kato, Shun Takizawa
In this paper we give an estimate for the solution to the Schrödinger equation with sub-quadratic potentials in modulation spaces by the norm of the initial functions in Wiener-Ama…

Singularities for solutions to time dependent Schrödingier equations with sub-quadratic potential
Keiichi Kato, Shingo Ito
In this article, we determine the wave front sets of solutions to time dependent Schrödinger equations with a sub-quadratic potential by using the representation of the Schrdingier…
