Global regularity of second order twisted differential operators
Ernesto Buzano, Alessandro Oliaro
In this paper we characterize global regularity in the sense of Shubin of twisted partial differential operators of second order in dimension . These operators form a class cont…
Cohen class of time-frequency representations and operators: boundedness and uncertainty principles
Paolo Boggiatto, Evanthia Carypis, Alessandro Oliaro
This paper presents a proof of an uncertainty principle of Donoho-Stark type involving -concentration of localization operators. More general operators associated with…
The Gabor wave front set in spaces of ultradifferentiable functions
Chiara Boiti, David Jornet, Alessandro Oliaro
Given a non-quasianalytic subadditive weight function we consider the weighted Schwartz space and the short-time Fourier transform on , $\mathcal…
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…
