Embeddings of $α$ -modulation spaces

Joachim Toft, Patrik Wahlberg

We show upper and lower embeddings of $α_{1}$ -modulation spaces in $α_{2}$ -modulation spaces for $0 \leq α_{1} \leq α_{2} \leq 1$ , and prove partial results on the sharpness of the embeddi…

Representations of almost periodic pseudodifferential operators and applications in spectral theory

Patrik Wahlberg

The paper concerns algebras of almost periodic pseudodifferential operators on $R^{d}$ with symbols in Hörmander classes. We study three representations of such algebras, one…

Almost periodic pseudodifferential operators and Gevrey classes

Alessandro Oliaro, Luigi Rodino, Patrik Wahlberg

We study almost periodic pseudodifferential operators acting on almost periodic functions $G_{\rm ap}^s(\rr d)$ of Gevrey regularity index $s \geq 1$ . We prove that almost periodic…
