Three solutions for quasilinear equations in Rn near resonance

open access: yesElectronic Journal of Differential Equations, 2001
We use minimax methods to prove the existence of at least three solutions for a quasilinear elliptic equation in $mathbb {R}^n$ near resonance.

On a class of semilinear elliptic problems near critical growth

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
We use Minimax Methods and explore compact embedddings in the context of Orlicz and Orlicz-Sobolev spaces to get existence of weak solutions on a class of semilinear elliptic equations with nonlinearities near critical growth. We consider both biharmonic

Existence of infinitely many periodic solutions for second-order nonautonomous Hamiltonian systems

open access: yesElectronic Journal of Differential Equations, 2015
By using minimax methods and critical point theory, we obtain infinitely many periodic solutions for a second-order nonautonomous Hamiltonian systems, when the gradient of potential energy does not exceed linear growth.

Periodic solutions of non-autonomous second order systems with p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2009
We prove the existence of periodic solutions for non-autonomous second order systems with p-Laplacian. Our main tools are the minimax methods in critical point theory. Our results are new, even when p=2.

Periodic solutions for nonautonomous second order Hamiltonian systems with sublinear nonlinearity

open access: yesBoundary Value Problems, 2011
Some existence and multiplicity of periodic solutions are obtained for nonautonomous second order Hamiltonian systems with sublinear nonlinearity by using the least action principle and minimax methods in critical point theory.

Existence of periodic solutions for non-autonomous second-order Hamiltonian systems

open access: yesElectronic Journal of Differential Equations, 2013
The purpose of this paper is to study the existence of periodic solutions for a class of non-autonomous second order Hamiltonian systems. New results are obtained by using the least action principle and the minimax methods, without the so-called Ahmad-
