Existence and multiplicity of solutions for a class of new nonlocal problem with indefinite potential

open access: yesDemonstratio Mathematica
This paper is devoted to study a class of new nonlocal problem with indefinite potential. Using linking theorem and symmetric mountain pass theorem, the existence and multiplicity of solutions to this problem are obtained.

Multiple Solutions for a Class of Fractional Schrödinger-Poisson System

open access: yesJournal of Function Spaces, 2019
We investigate a class of fractional Schrödinger-Poisson system via variational methods. By using symmetric mountain pass theorem, we prove the existence of multiple solutions.

Mountain Pass Theorem With infinite symmetry

open access: yes, 2012
We extend a work of Bartsch, Clapp and Puppe on the Mountain pass theorems. We consider functionals invariant with respect to infinite discrete groups satisfying a maximality condition on the finite subgroups.

Soliton Solutions for Quasilinear Schrödinger Equations

open access: yesJournal of Applied Mathematics, 2013
By using a change of variables, we get new equations, whose respective associated functionals are well defined in and satisfy the geometric hypotheses of the mountain pass theorem. Using this fact, we obtain a nontrivial solution.

Normalized solutions for the Fractional Hardy critical Schrödinger system

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
In this paper, we consider the existence and multiplicity of normalized solutions for the following fractional Schrödinger system with Hardy critical coupled term: \begin{equation*} \left\{\begin{aligned} &(-\Delta)^{s}u+\lambda_{1}u=|u|^{p-2}u+\frac ...

Existence of solutions for Kirchhoff type equations

open access: yesElectronic Journal of Differential Equations, 2015
In this article, we prove the existence of solutions for Kirchhoff type equations with Dirichlet boundary-value condition. We use the Mountain Pass Theorem in critical point theory, without the (PS) condition.
