Sensitivity analysis for generalized quasi-variational relation problems in locally G-convex spaces
Nguyễn Văn Hùng · Fixed Point Theory and Applications · 2012
In this paper, we study generalized quasi-variational relation problems in locally G -convex spaces. Using the Kakutani-Fan-Glicksberg fixed-point theorem for upper semicontinuous set-valued mapping with nonempty closed acyclic values, we establish an existence theorem of a solution set for these problems. Moreover, the stability and closedness of the solution set for these problems are also obtained. The results presented in the paper improve and extend the main results in the literature.
