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…
