Pseudo-differential operators with isotropic symbols, Wick and anti-Wick operators, and hypoellipticity
Nenad Teofanov, Joachim Toft, Patrik Wahlberg
We study the link between pseudo-differential operators and Wick operators via the Bargmann transform. We deduce a formula for the symbol of the Wick operator in terms of the short…
The Gabor wave front set
Luigi Rodino, Patrik Wahlberg
We define the Gabor wave front set of a tempered distribution in terms of rapid decay of its Gabor coefficients in a conic subset of the phase space. We show the incl…
Representations of almost periodic pseudodifferential operators and applications in spectral theory
Patrik Wahlberg
The paper concerns algebras of almost periodic pseudodifferential operators on 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 . We prove that almost periodic…
