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.

New Quantitative Deformation Lemma and New Mountain Pass Theorem

open access: yes, 2014
In this paper, we obtain a new quantitative deformation Lemma so that we can obtain more critical points, especially for supinf critical value $c_1$, $x= ^{-1}(c_1)$ is a new critical point. For $infmax$ critical value $c_2$, we can obtain two new critical points $x = 0$ (valley point) and $x = e$(peak point) ,comparing with Willem's variant of the ...

A Mountain-pass Theorem in Hyperbolic Space and its Application

open access: yes, 2022
We develop a min-max theory for certain complete minimal hypersurfaces in hyperbolic space. In particular, we show that given two strictly stable minimal hypersurfaces that are both asymptotic to the same ideal boundary, there is a new one trapped between the two.

Existence Results for a px-Kirchhoff-Type Equation without Ambrosetti-Rabinowitz Condition

open access: yesJournal of Applied Mathematics, 2013
We consider the existence and multiplicity of solutions for the px-Kirchhoff-type equations without Ambrosetti-Rabinowitz condition. Using the Mountain Pass Lemma, the Fountain Theorem, and its dual, the existence of solutions and infinitely many ...

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.
