Spectral identities and smoothing estimates for evolution operators

Matania Ben-Artzi, Michael Ruzhansky, Mitsuru Sugimoto

Smoothing (and decay) spacetime estimates are discussed for evolution groups of self-adjoint operators in an abstract setting. The basic assumption is the existence (and weak conti…

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^…
