Abstract

We prove the existence of three distinct nontrivial solutions for a class of semilinear elliptic variational inequalities involving a superlinear nonlinearity. The approach is variational and is based on linking and del-theorems. Some nonstandard adaptations are required to overcome the lack of the Palais-Smale condition. (c) 2005 Elsevier Inc.
