Boundedness of propagators for Dirac equations with potentials on Wiener amalgam spaces
Shun Takizawa
In this paper we prove boundedness of propagators for Dirac equations with unbounded time-dependent potentials on Wiener amalgam spaces. In particular we deal with class of potenti…

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…
