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…
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…
Excess-continuous prox-regular sweeping processes
Vincenzo Recupero, Federico Stra
In this paper we consider the Moreau's sweeping processes driven by a time dependent prox-regular set which is continuous in time with respect to the asymmetric distance …
