In this work we study the existence of solutions for the following class of quasilinear elliptic
equations− div A (| x|)|∇ u| N− 2∇ u= Q (| x|) f (u), in RN, where N≥ 2 and f has critical …

Quasilinear PDEs, Interpolation Spaces and Hölderian mappings

I Ahmed, A Fiorenza, MR Formica, A Gogatishvili… - Analysis …, 2023 - Springer
As in the work of Tartar, we develop here some new results on nonlinear interpolation of α-
Hölderian mappings between normed spaces, by studying the action of the mappings on K …

Korn and Poincaré-Korn inequalities: A different perspective

G Di Fratta, F Solombrino - Proceedings of the American Mathematical …, 2024 - ams.org
We present a concise point of view on the first and the second Korn's inequality for general
exponent $ p $ and for a class of domains that includes Lipschitz domains. Our argument is …

Symmetry properties of minimizers of a perturbed Dirichlet energy with a boundary penalization

G Di Fratta, A Monteil, V Slastikov - SIAM Journal on Mathematical Analysis, 2022 - SIAM
We consider S^2-valued maps on a domain Ω⊂R^N minimizing a perturbation of the
Dirichlet energy with vertical penalization in Ω and horizontal penalization on ∂Ω. We first …

A modular Poincaré–Wirtinger inequality for Sobolev spaces with variable exponents

E Davoli, G Di Fratta, A Fiorenza, L Happ - Nonlinear Differential Equations …, 2024 - Springer
In the context of Sobolev spaces with variable exponents, Poincaré–Wirtinger inequalities
are possible as soon as Luxemburg norms are considered. On the other hand, modular …

On a multiscale formulation for multiperforated plates

K Schmidt, S Pfaff - arXiv preprint arXiv:2407.02185, 2024 - arxiv.org
Multiperforated plates exhibit high gradients and a loss of regularity concentrated in a
boundary layer for which a direct numerical simulation becomes very expensive. For elliptic …

Internal waves in a 2D subcritical channel

Z Li, J Wang, J Wunsch - arXiv preprint arXiv:2411.14587, 2024 - arxiv.org
We study scattering and evolution aspects of linear internal waves in a two dimensional
channel with subcritical bottom topography. We define the scattering matrix for the stationary …

Geometric logarithmic-Hardy and Hardy-Poincar\'e inequalities on stratified groups

M Chatzakou - arXiv preprint arXiv:2402.10279, 2024 - arxiv.org
We develop a unified strategy to obtain the geometric logarithmic Hardy inequality on any
open set M of a stratified group, provided the validity of the Hardy inequality in this setting …

G DI FRATTA, A FIORENZA - researchgate.net
This paper builds upon the Caffarelli-Kohn-Nirenberg (CKN) weighted interpolation
inequalities, which are fundamental tools in partial differential equations (PDEs) and …
