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 …
Deterministic particle method for nonlinear nonlocal scalar balance equations
Emanuela Radici, Federico Stra
We study a deterministic particle scheme to solve a scalar balance equation with nonlocal interaction and nonlinear mobility used to model congested dynamics. The main novelty with…
Stability of quasi-entropy solutions of non-local scalar conservation laws
Elio Marconi, Emanuela Radici, Federico Stra
We prove the stability of entropy solutions of nonlinear conservation laws with respect to perturbations of the initial datum, the space-time dependent flux and the entropy inequal…
Entropy solutions of non-local scalar conservation laws with congestion via deterministic particle method
Emanuela Radici, Federico Stra
We develop deterministic particle schemes to solve non-local scalar conservation laws with congestion. We show that the discrete approximations converge to the unique entropy solut…
First order expansion in the semiclassical limit of the Levy-Lieb functional
Maria Colombo, Simone Di Marino, Federico Stra
We prove the conjectured first order expansion of the Levy-Lieb functional in the semiclassical limit, arising from Density Functional Theory (DFT). This is accomplished by interpr…
Lagrangian discretization of crowd motion and linear diffusion
Hugo Leclerc, Quentin Mérigot, Filippo Santambrogio +1
We study a model of crowd motion following a gradient vector field, with possibly additional interaction terms such as attraction/repulsion, and we present a numerical scheme for i…
Linear Lipschitz and extension operators through random projection
Elia Bruè, Simone Di Marino, Federico Stra
We construct a regular random projection of a metric space onto a closed doubling subset and use it to linearly extend Lipschitz and functions. This way we prove more directl…
A PDE approach to a 2-dimensional matching problem
Luigi Ambrosio, Federico Stra, Dario Trevisan
We prove asymptotic results for 2-dimensional random matching problems. In particular, we obtain the leading term in the asymptotic expansion of the expected quadratic transportati…
Weak and strong convergence of derivations and stability of flows with respect to MGH convergence
Luigi Ambrosio, Federico Stra, Dario Trevisan
This paper is devoted to the study of weak and strong convergence of derivations, and of the flows associated to them, when dealing with a sequence of metric measure structures (X,…
Counterexamples in multimarginal optimal transport with Coulomb cost and spherically symmetric data
Maria Colombo, Federico Stra
We disprove a conjecture in Density Functional Theory, relative to multimarginal optimal transport maps with Coulomb cost. We also provide examples of maps satisfying optimality co…
