Variational inequality problems in H‐spaces
Akrur Behera, Prasanta Kumar Das · International Journal of Mathematics and Mathematical Sciences · 2006
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.
