The stability landscape in wave-packet scattering: geometric rigidity and sharp Sobolev thresholds
Max Getter, S. Ivan Trapasso
A central problem in harmonic analysis is to understand how frequency resolution constrains stability under nonlinear changes of coordinates. Motivated by Mallat's wavelet scatteri…

A quantum harmonic analysis approach to nonlinear time-frequency concentration
Erling A. T. Svela, S. Ivan Trapasso
We study nonlinear concentration problems for time-frequency distributions in the Cohen class. Using recent techniques from quantum harmonic analysis (QHA) we provide both positive…

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…
