A note on the HRT conjecture and a new uncertainty principle for the short-time Fourier transform
Fabio Nicola, S. Ivan Trapasso
In this note we provide a negative answer to a question raised by M. Kreisel concerning a condition on the short-time Fourier transform that would imply the HRT conjecture. In part…

Time-frequency analysis of the Dirac equation
S. Ivan Trapasso
The purpose of this paper is to investigate several issues concerning the Dirac equation from a time-frequency analysis perspective. More precisely, we provide estimates in weighte…

Linear perturbations of the Wigner transform and the Weyl quantization
Dominik Bayer, Elena Cordero, Karlheinz Gröchenig +1
We study a class of quadratic time-frequency representations that, roughly speaking, are obtained by linear perturbations of the Wigner transform. They satisfy Moyal's formula by d…
