On Neumann hemivariational inequalities

open access: yesAbstract and Applied Analysis, Volume 7, Issue 2, Page 103-112, 2002., 2002
We derive a nontrivial solution for a Neumann noncoercive hemivariational inequality using the critical point theory for locally Lipschitz functionals. We use the Mountain‐Pass theorem due to Chang (1981).

Three topological problems about integral functionals on Sobolev spaces

open access: yes, 2004
In this paper, I propose some problems, of topological nature, on the energy functional associated to the Dirichlet problem -\Delta u = f(x,u) in Omega, u restricted to the boundary of Omega is 0.

On the location of the peaks of least‐energy solutions to semilinear Dirichlet problems with critical growth

open access: yesAbstract and Applied Analysis, Volume 7, Issue 10, Page 547-561, 2002., 2002
We study the location of the peaks of solution for the critical growth problem −ε 2Δu+u=f(u)+u 2*−1, u > 0 in Ω, u = 0 on ∂Ω, where Ω is a bounded domain; 2* = 2N/(N − 2), N ≥ 3, is the critical Sobolev exponent and f has a behavior like up, 1 < p < 2* − 1.

Sign‐changing and multiple solutions for the p‐Laplacian

open access: yesAbstract and Applied Analysis, Volume 7, Issue 12, Page 613-625, 2002., 2002
We obtain a positive solution, a negative solution, and a sign‐changing solution for a class of p‐Laplacian problems with jumping nonlinearities using variational and super‐subsolution methods.

Domain perturbation method and local minimizers to Ginzburg‐Landau functional with magnetic effect

open access: yesAbstract and Applied Analysis, Volume 5, Issue 2, Page 101-112, 2000., 2000
We prove the existence of vortex local minimizers to Ginzburg‐Landau functional with a global magnetic effect. A domain perturbating method is developed, which allows us to extend a local minimizer on a nonsimply connected superconducting material to the local minimizer with vortex on a simply connected material.

Multiple solutions for weighted Kirchhoff equations involving critical Hardy-Sobolev exponent

open access: yesAdvances in Nonlinear Analysis, 2020
In this article, we consider a class of Kirchhoff equations with critical Hardy-Sobolev exponent and indefinite nonlinearity, which has not been studied in the literature. We prove very nicely that this equation has at least two solutions in ℝ3. And some
