Sharp Continuity Results for the Short-Time Fourier Transform and for Localization Operators
Elena Cordero, Fabio Nicola
We completely characterize the boundedness on spaces and on Wiener amalgam spaces of the short-time Fourier transform (STFT) and of a special class of pseudodifferential oper…

Pseudodifferential operators on , Wiener amalgam and modulation spaces
Elena Cordero, Fabio Nicola
We give a complete characterization of the continuity of pseudodifferential operators with symbols in modulation spaces , acting on a given Lebesgue space . Namely, w…
