Minimizers of one-dimensional regularization problems with linear and nonlinear total variation
Luca Lussardi, Marco Morandotti, Federico Stra
A study of the minimizers of one-dimensional Rudin-Osher-Fatemi-type functionals with linear or nonlinear total variation and fidelity term is undertaken. Conditions on the input d…

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…
