This paper studies three different approximation concepts in the context of n-person concave games. Formally, we establish the precise relationship between the notions of ε-Nash Equilibrium, $\hatε-approximate solution, and δ-near Nash equilibrium. We apply our results to the class of Lipschitz games and discrete network games respectively.

Keywords: ε-Nash Equilibrium, $\hatε-approximate solution, δ-near Nash Equilibrium, VI, Lipschitz games, Network games.
