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.

On a global implicit function theorem for locally Lipschitz maps via non-smooth critical point theory [PDF]

open access: yes, 2018
We prove a non-smooth generalization of the global implicit function theorem. More precisely we use the non-smooth local implicit function theorem and the non-smooth critical point theory in order to prove a non-smooth global implicit function theorem ...

A Saddle Point Theorem For Non-Smooth Functionals And Problems At Resonance [PDF]

open access: yes, 1996
We prove a saddle point theorem for locally Lipschitz functionals with arguments based on a version of the mountain pass theorem for such kind of functionals. This abstract result is applied to solve two different types of multivalued semilinear elliptic

Existence and Multiplicity of Fast Homoclinic Solutions for a Class of Nonlinear Second-Order Nonautonomous Systems in a Weighted Sobolev Space [PDF]

open access: yes, 2020
This paper is concerned with the following nonlinear second-order nonautonomous problem:( ) + ( )( ) − ∇ ( , ( )) + ∇ ( , ( )) = 0, where ∈ R, ∈ R , and , ∈ 1 (R × R , R) are not periodic in and : R → R is a continuous function and ( ) = ∫ 0 ( ) with lim

Positive solutions for anisotropic discrete boundary-value problems

open access: yesElectronic Journal of Differential Equations, 2013
Using mountain pass arguments and the Karsuh-Kuhn-Tucker Theorem, we prove the existence of at least two positive solution for anisotropic discrete Dirichlet boundary-value problems. Our results generalized and improve those in [16].
