Abstract
The concept of η-invex set is explored and the
concept of T-η-invex function is introduced.
These concepts are applied to the generalized vector variational
inequality problems in ordered topological vector spaces. The
study of variational inequality problems is extended to H-spaces and differentiable n-manifolds. The solution of
complementarity problem is also studied in the presence
of fixed points or Lefschetz number.
