On the convexity of the solution set of symmetric vector equilibrium problems
Ali P. Farajzadeh · Filomat · 2015
In this paper, without assumption of monotonicity and boundedness, we study existence results for a solution and the convexity of the solution set to the symmetric vector equilibrium problem for setvalued mappings in the setting of topological vector spaces. Our results improve the corresponding results in [9, 18, 19, 22, 28, 33, 36, 37].
