Nonautonomous Klein–Gordon–Maxwell systems in a bounded domain

open access: yesAdvances in Nonlinear Analysis, 2014
This paper deals with the Klein–Gordon–Maxwell system in a bounded spatial domain with a nonuniform coupling. We discuss the existence of standing waves in equilibrium with a purely electrostatic field, assuming homogeneous Dirichlet boundary conditions ...

The Brezis–Nirenberg problem for nonlocal systems

open access: yesAdvances in Nonlinear Analysis, 2016
By means of variational methods we investigate existence, nonexistence as well as regularity of weak solutions for a system of nonlocal equations involving the fractional laplacian operator and with nonlinearity reaching the critical growth and ...

Klein–Gordon–Maxwell Systems with Nonconstant Coupling Coefficient

open access: yesAdvanced Nonlinear Studies, 2018
We study a Klein–Gordon–Maxwell system in a bounded spatial domain under Neumann boundary conditions on the electric potential. We allow a nonconstant coupling coefficient. For sufficiently small data, we find infinitely many static solutions.

Fourth order elliptic system with dirichlet boundary condition

open access: yes, 2011
We investigate the multiplicity of the solutions of the fourth order elliptic system with Dirichlet boundary condition. We get two theorems. One theorem is that the fourth order elliptic system has at least two nontrivial solutions when λ k < c &

Existence and multiplicity of solutions for a class of superlinear elliptic systems

open access: yesAdvances in Nonlinear Analysis, 2018
In this paper, we establish the existence and multiplicity of solutions for a class of superlinear elliptic systems without Ambrosetti and Rabinowitz growth condition. Our results are based on minimax methods in critical point theory.
