Characterization of generalized Orlicz spaces
Rita Ferreira, Peter Hästö, Ana Margarida Ribeiro
The norm in classical Sobolev spaces can be expressed as a difference quotient. This expression can be used to generalize the space to the fractional smoothness case. Because the d…
A chromaticity-brightness model for color images denoising in a Meyer's "u+v" framework
Rita Ferreira, Irene Fonseca, M. Luisa Mascarenhas
A variational model for imaging segmentation and denoising color images is proposed. The model combines Meyer's "u+v" decomposition with a chromaticity-brightness framework and is…
Existence of weak solutions to stationary mean-field games through variational inequalities
Rita Ferreira, Diogo Gomes
Here, we consider stationary monotone mean-field games (MFGs) and study the existence of weak solutions. First, we introduce a regularized problem that preserves the monotonicity.…
