-convergence involving nonlocal gradients with varying horizon: Recovery of local and fractional models

Javier Cueto, Carolin Kreisbeck, Hidde Schönberger

This work revolves around the rigorous asymptotic analysis of models in nonlocal hyperelasticity. The corresponding variational problems involve integral functionals depending on n…

Nonlocal gradients: Fundamental theorem of calculus, Poincaré inequalities and embeddings

José Carlos Bellido, Carlos Mora-Corral, Hidde Schönberger

We address the study of nonlocal gradients defined through general radial kernels . Our investigation focuses on the properties of the associated function spaces, which depend o…

Non-constant functions with zero nonlocal gradient and their role in nonlocal Neumann-type problems

Carolin Kreisbeck, Hidde Schönberger

This work revolves around properties and applications of functions whose nonlocal gradient, or more precisely, finite-horizon fractional gradient, vanishes. Surprisingly, in contra…

A variational theory for integral functionals involving finite-horizon fractional gradients

Javier Cueto, Carolin Kreisbeck, Hidde Schönberger

The center of interest in this work are variational problems with integral functionals depending on special nonlocal gradients. The latter correspond to truncated versions of the R…

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…
