The concentration-compactness principles for Ws,p(·,·)(ℝN) and application

open access: yesAdvances in Nonlinear Analysis, 2020
We obtain a critical imbedding and then, concentration-compactness principles for fractional Sobolev spaces with variable exponents. As an application of these results, we obtain the existence of many solutions for a class of critical nonlocal problems ...

Sign-Changing Solutions for the One-Dimensional Non-Local sinh-Poisson Equation

open access: yesAdvanced Nonlinear Studies, 2020
We study the existence of sign-changing solutions for a non-local version of the sinh-Poisson equation on a bounded one-dimensional interval I, under Dirichlet conditions in the exterior of I.

Notes on continuity result for conformable diffusion equation on the sphere: The linear case

open access: yesDemonstratio Mathematica, 2022
In this article, we are interested in the linear conformable diffusion equation on the sphere. Our main goal is to establish some results on the continuity problem with respect to fractional order.

A complete study of the lack of compactness and existence results of a fractional Nirenberg equation via a flatness hypothesis, I [PDF]

open access: yes, 2014
In this paper, we consider a nonlinear critical problem involving the fractional Laplacian operator arising in conformal geometry, namely the prescribed -curvature problem on the standard n- sphere n ≥ 2.

All functions are locally $s$-harmonic up to a small error [PDF]

open access: yes, 2014
We show that we can approximate every function $f\in C^{k}(\bar{B_1})$ with a $s$-harmonic function in $B_1$ that vanishes outside a compact set. That is, $s$-harmonic functions are dense in $C^{k}_{\rm{loc}}$.

Regularity and Bernstein-type results for nonlocal minimal surfaces [PDF]

open access: yes, 2013
We prove that, in every dimension, Lipschitz nonlocal minimal surfaces are smooth. Also, we extend to the nonlocal setting a famous theorem of De Giorgi stating that the validity of Bernstein's theorem in dimension $n+1$ is a consequence of the ...
