Solitary waves for a coupled nonlinear Schrodinger system with dispersion management

open access: yesElectronic Journal of Differential Equations, 2010
We consider a system of coupled nonlinear Schrodinger equations with periodically varying dispersion coefficient that arises in the context of fiber-optics communication.

Homoclinic solutions of difference equations with variable exponents

open access: yes, 2011
We study the existence of homoclinic solutions for a class of non-homogeneous difference equation with periodic coefficients. Our proofs rely on the critical point theory combined with adequate variational techniques, which are mainly based on the ...

Multiplicity of ground state solutions for discrete nonlinear Schrodinger equations with unbounded potentials

open access: yesElectronic Journal of Differential Equations, 2017
The discrete nonlinear Schrodinger equation is a nonlinear lattice system that appears in many areas of physics such as nonlinear optics, biomolecular chains and Bose-Einstein condensates.

Existence of solutions of fractional p-Laplacian systems with different critical Sobolev-Hardy exponents

open access: yes
In this paper, we investigate a fractional p-Laplacian system with different critical Sobolev-Hardy exponents. By variational methods and the Mountain-Pass lemma, positive minimizers of the related best Sobolev constants and the existence of positive ...
