On the Existence of Nontrivial Solutions of Inequalities in Orlicz-Sobolev Spaces
This paper is about an alternate variational inequality formulation for the boundary value problem −div(a(|∇u|)∇u)+∂uG(x,u)∋0 in Ω,u=0 on ∂Ω, where the principal part may have non-polynomial or very slow growth. As a consequence of this formulation, we can apply abstract nonsmooth linking theorems to study the existence and multiplicity of nontrivial solutions to the above problem.
