On double phase Kirchhoff problems with singular nonlinearity

open access: yesAdvances in Nonlinear Analysis, 2023
In this paper, we study multiplicity results for double phase problems of Kirchhoff type with right-hand sides that include a parametric singular term and a nonlinear term of subcritical growth.

Singular measure as principal eigenfunction of some nonlocal operators

open access: yes, 2013
In this paper, we are interested in the spectral properties of the generalised principal eigenvalue of some nonlocal operator. That is, we look for the existence of some particular solution $(\lambda,\phi)$ of a nonlocal operator. $$\int_{\O}K(x,y)\phi(y)

Uniqueness and radial symmetry for an inverse elliptic equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 48, Page 3047-3052, 2003., 2003
We consider an inverse rearrangement semilinear partial differential equation in a 2‐dimensional ball and show that it has a unique maximizing energy solution. The solution represents a confined steady flow containing a vortex and passing over a seamount. Our approach is based on a rearrangement variational principle extensively developed by G.

Leray-Schauder’s solution for a nonlocal problem in a fractional Orlicz-Sobolev space

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
Via Leray-Schauder’s nonlinear alternative, we obtain the existence of a weak solution for a nonlocal problem driven by an operator of elliptic type in a fractional Orlicz-Sobolev space, with homogeneous Dirichlet boundary conditions.

On a system of multi-component Ginzburg-Landau vortices

open access: yesAdvances in Nonlinear Analysis, 2023
We study the asymptotic behavior of solutions for nn-component Ginzburg-Landau equations as ε→0\varepsilon \to 0. We prove that the minimizers converge locally in any Ck{C}^{k}-norm to a solution of a system of generalized harmonic map equations.

Existence of entire explosive positive radial solutions of quasilinear elliptic systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 46, Page 2907-2927, 2003., 2003
Our main purpose is to establish that entire explosive positive radial solutions exist for quasilinear elliptic systems. The main results of the present paper are new and extend previous results.

Eigencurves of the p(·)-Biharmonic operator with a Hardy-type term

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
This paper is devoted to the study of the homogeneous Dirichlet problem for a singular nonlinear equation which involves the p(·)-biharmonic operator and a Hardy-type term that depend on the solution and with a parameter λ.

Estimates for the volume of a Lorentzian manifold

open access: yes, 2002
We prove new estimates for the volume of a Lorentzian manifold and show especially that cosmological spacetimes with crushing singularities have finite volume.Comment: 8 pages, a pdf version of the preprint can also be retrieved from http://www.math ...

Uniqueness of semilinear elliptic inverse problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 67, Page 4217-4227, 2003., 2003
We consider the uniqueness of the inverse problem for a semilinear elliptic differential equation with Dirichlet condition. The necessary and sufficient condition of unique solution is obtained. We improved the results obtained by Isakov and Sylvester (1994) for the same problem.
