Highly oscillatory unimodular Fourier multipliers on modulation spaces
Fabio Nicola, Eva Primo, Anita Tabacco
We study the continuity on the modulation spaces of Fourier multipliers with symbols of the type , for some real-valued function . A number of results ar…
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…
Compactness of Fourier Integral Operators on weighted modulation spaces
Carmen Fernández, Antonio Galbis, Eva Primo
Using the matrix representation of Fourier integral operators with respect to a Gabor frame, we study their compactness on weighted modulation spaces. As a consequence, we recover…
Unconditionally convergent multipliers and Bessel sequences
Carmen Fernández, Antonio Galbis, Eva Primo
We prove that every unconditionally summable sequence in a Hilbert space can be factorized as the product of a square summable scalar sequence and a Bessel sequence. Some consequen…
