Indistinguishability in cooperative games

Game Theory has proven to be a useful tool for modelling decision problems in competitive and collaborative environments. Cooperative games, in turn, promote the bargaining and the formation of coalitions, and deals with problems as the redistribution of gained payo between members of coalitions. This paper introduces the concept of indistinguishability among players, providing constructive methods for computing the T -indistinguishability operator associated to any cooperative game.
