Non-local functionals related to the total variation and connections with Image Processing
Haim Brezis, Hoai-Minh Nguyen
We present new results concerning the approximation of the total variation, , of a function by non-local, non-convex functionals of the form $$ Λ_δu = \int_Ω…
Density in
Haïm Brezis, Petru Mironescu
Let be a smooth bounded domain in , $0\textless{}s\textless{}\infty$ and $1\le p\textless{}\infty$. We prove that is den…
On the optimality of shape and data representation in the spectral domain
Yonathan Aflalo, Haim Brezis, Ron Kimmel
A proof of the optimality of the eigenfunctions of the Laplace-Beltrami operator (LBO) in representing smooth functions on surfaces is provided and adapted to the field of applied…
BMO-type norms related to the perimeter of sets
Luigi Ambrosio, Jean Bourgain, Haim Brezis +1
In this paper we consider an isotropic variant of the -type norm recently introduced by Bourgain, Brezis and Mironescu. We prove that, when considering characteristic function…
