Multiplicity results for a perturbed elliptic Neumann problem.
Infinitely many solutions for perturbed hemivariational inequalities.
Molteplicity of Solutions for Sturm-Liouville Problems
The existence of multiple solutions to a Sturm-Liouville boundary value problem is presented. The approach adopted is based on multiple critical points theorems.
