Sensitivity analysis for generalized quasi-variational relation problems in locally G-convex spaces

Abstract

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.

The existence and stability of solutions for symmetric generalized quasi-variational inclusion problems

“…In recent years, a lot of results for existence of solutions and stability of solutions for symmetric vector quasiequilibrium problems, vector quasi-equilibrium problems, vector quasi-variational inequality problems and optimization problems have been established by many authors in different ways. For example, equilibrium problems [1-10, 15-17, 19, 23-25, 29, 34, 35, 37, 40, 41], variational inequality problems [25,30,31,36,42,43], optimization problems [35,42,43], variational relation problems [12,13,27,28,32,33] and the references therein.…”

On a generalized variational inequality problem

“…Similar conditions like in Theorem 2.1 could be used to obtain existence results for some other variational problems, for instance for problems of the sort treated in [2], [12][13][14], [16].…”

A Note on the Generalized Nonlinear Vector Variational-Like Inequality Problem

“…In the subsequent period, generalized quasi-variational inequalities were studied by Hung and others [10][11][12]. In 2017, Irfan et al introduced a new generalized variationallike inclusion problem involving relaxed monotone operators [13].…”
