On Fourier integral operators with Hölder-continuous phase
Elena Cordero, Fabio Nicola, Eva Primo
We study continuity properties in Lebesgue spaces for a class of Fourier integral operators arising in the study of the Boltzmann equation. The phase has a Hölder-type singularity…
A characterization of modulation spaces by symplectic rotations
Elena Cordero, Maurice De Gosson, Fabio Nicola
This note contains a new characterization of modulation spaces , , by symplectic rotations. Precisely, instead to measure the time-frequency…
On the Positivity of Trace Class Operators
Elena Cordero, Maurice de Gosson, Fabio Nicola
The characterization of positivity properties of Weyl operators is a notoriously difficult problem, and not much progress has been made since the pioneering work of Kastler, Loupia…
Strichartz estimates for the metaplectic representation
Alessandra Cauli, Fabio Nicola, Anita Tabacco
Strichartz estimates are a manifestation of a dispersion phenomenon, exhibited by certain partial differential equations, which is detected by suitable Lebesgue space norms. In mos…
Kernel theorems for modulation spaces
Elena Cordero, Fabio Nicola
We deal with kernel theorems for modulation spaces. We completely characterize the continuity of a linear operator on the modulation spaces for every , by…
