Structural changes in nonlocal denoising models arising through bi-level parameter learning
Elisa Davoli, Rita Ferreira, Carolin Kreisbeck +1
We introduce a unified framework based on bi-level optimization schemes to deal with parameter learning in the context of image processing. The goal is to identify the optimal regu…
A Potential Approach for Planning Mean-Field Games in One Dimension
Tigran Bakaryan, Rita Ferreira, Diogo Gomes
This manuscript discusses planning problems for first- and second-order one-dimensional mean-field games (MFGs). These games are comprised of a Hamilton-Jacobi equation coupled wit…
Homogenization of quasi-crystalline functionals via two-scale-cut-and-project convergence
Rita Ferreira, Irene Fonseca, Raghavendra Venkatraman
We consider a homogenization problem associated with quasi-crystalline multiple integrals of the form \begin{equation*} \begin{aligned} u_\varepsilon\in L^p(Ω;\mathbb{R}^d) \mapsto…
Uniform estimates for the planning problem with potential
Tigran Bakaryan, Rita Ferreira, Diogo Gomes
In this paper, we study a priori estimates for a first-order mean-field planning problem with a potential. In the theory of mean-field games (MFGs), a priori estimates play a cruci…
Existence of weak solutions to time-dependent mean-field games
Rita Ferreira, Diogo Gomes, Teruo Tada
Here, we establish the existence of weak solutions to a wide class of time-dependent monotone mean-field games (MFGs). These MFGs are given as a system of degenerate parabolic equa…
Two-scale homogenization of a stationary mean-field game
Rita Ferreira, Diogo Gomes, Xianjin Yang
In this paper, we characterize the asymptotic behavior of a first-order stationary mean-field game (MFG) with a logarithm coupling, a quadratic Hamiltonian, and a periodically osci…
