Nonlinear operations on a class of modulation spaces

Tomoya Kato, Mitsuru Sugimoto, Naohito Tomita

We discuss when the nonlinear operation $f \mapsto F (f)$ maps the modulation space $M_{s}^{p, q} (R^{n})$ ( $1 \leq p, q \leq \infty$ ) to the same space again. It is known that $M^…

A remark on the Schrödinger operator on Wiener amalgam spaces

Tomoya Kato, Naohito Tomita

In this paper, we study the boundedness of the Schrödinger operator $e^{i Δ}$ on Wiener amalgam spaces and determine its optimal condition.
