An eigenvalue problem for elliptic variational inequalities is considered. The existence of multiple solutions is proved, when the operator is a small (non-odd) perturbation of an odd operator. To this aim, techniques of nonsmooth critical point theory are employed.

Abstract
An eigenvalue problem for elliptic variational inequalities is considered. The existence of multiple solutions is proved, when the operator is a small (non-odd) perturbation of an odd operator. To this aim, techniques of nonsmooth critical point theory are employed.
