Before revision: We provide an epistemic foundation for the core of a cooperative game by proof theory . Given a cooperative game, we first transform each payoff vector into a decision problem ( accept or reject ) for each player .
After revision: We provide an epistemic foundation for the core of a cooperative game by proof theory by studying the knowledge needed for players to unanimously accept only core payoffs. We first transform each payoff vector into a decision problem ( accept or reject ) for each player .
