Existence and continuity for the ε-approximation equilibrium problems in Hadamard spaces
Pakkapon Preechasilp · Journal of Inequalities and Applications · 2016
In this paper, the existence of ε -approximate equilibrium points for a bifunction is proved under suitable conditions in the framework of a Hadamard space. We also give the sufficient conditions for the continuity of ε -approximate solution maps to equilibrium problems. Then we apply our results to constrained minimization problems and Nash-equilibrium problems.
