On the existence of optimizers for nonlinear time-frequency concentration problems: the Born--Jordan distribution
Federico Stra, Erling A. T. Svela, S. Ivan Trapasso
We study the concentration problem for the Born--Jordan distribution in dimension , thus extending the one-dimensional analysis in [Stra-Svela-Trapasso, J. Math. Pures A…
On the existence of optimizers for nonlinear time-frequency concentration problems: the Wigner distribution
Federico Stra, Erling A. T. Svela, S. Ivan Trapasso
We prove that, for any measurable phase space subset with and any , the nonlinear concentration problem $$ \sup_{f \in L^2…
An introduction to the Gabor wave front set
Luigi Rodino, S. Ivan Trapasso
In this expository note we present an introduction to the Gabor wave front set. As is often the case, this tool in microlocal analysis has been introduced and reinvented in differe…
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…
