well known refinements of the Nash equilibrium, namely, perfect Nash equilibrium and proper Nash equilibrium, are special … Nash equilibrium is shown to exist for every game. In symmetric bimatrix games, our results imply the existence of a … symmetric proper equilibrium. Applying our results to the field of evolutionary game theory yields a refinement of the …

players to which ν will become disconnected. We focus on unilateral link formation and Nash equilibrium. We show existence of …

with unawareness, define equilibrium, and prove existence. We show how equilibria are extended naturally from lower to … investigate the robustness of equilibria to uncertainty about opponents' awareness of actions. We show that a Nash equilibrium of …
