Abstract

We establish several new existence theorems for nonlinear variational inequalities with generalized positively homogeneous functions. The results presented here are general enough to include two More existence theorems of complementarity problems as special cases. We also establish an existence result for nonlinear complementarity problems with an exceptional regularity map. The concept of an exceptional family for a variational inequality plays a key role in our analysis.
