Fractional Hardy inequalities on open sets

Abdelrazek Dieb, Remi Yvant Temgoua

Let be a bounded open set of class in and . We study a family of fractional Hardy-type inequalities \begin{equation} \frac{c_{N,s…

A note on a Pohozaev identity for the fractional Green function

Abdelrazek Dieb, Isabella Ianni

We get a Pohozaev-type identity for the fractional Green function, which extends to the fractional setting a classical result by Brezis and Peletier. Our result complements with so…

Uniqueness and nondegeneracy of least-energy solutions to fractional Dirichlet problems

Abdelrazek Dieb, Isabella Ianni, Alberto Saldaña

We prove the uniqueness and nondegeneracy of least-energy solutions of a fractional Dirichlet semilinear problem in sufficiently large balls and in more general symmetric domains.…

Uniqueness and nondegeneracy for Dirichlet fractional problems in bounded domains via asymptotic methods

Abdelrazek Dieb, Isabella Ianni, Alberto Saldaña

We consider positive solutions of a fractional Lane-Emden type problem in a bounded domain with Dirichlet conditions. We show that uniqueness and nondegeneracy hold for the asympto…

Attainability of the fractional Hardy constant with nonlocal mixed boundary conditions. Applications

Boumediene Abdellaoui, Ahmed Attar, Abdelrazek Dieb +1

The first goal of this paper is to study necessary and sufficient conditions to obtain the attainability of the \textit{fractional Hardy inequality } $$Λ_{N}\equivΛ_{N}(Ω):=\inf_{\…

A nonlocal concave-convex problem with nonlocal mixed boundary data

Boumediene Abdellaoui, Abdelrazek Dieb, Enrico Valdinoci

The aim of this paper is to study a nonlocal problem with a mixed Dirichlet-Neumann exterior condition. We prove existence, nonexistence and multiplicity of positive energy solutio…
