WebbIn Shapley’s [ 2] work, the balanced condition is defined for the coalitional vector system , which specifies the weight of each participant in each coalition. For the core to be nonempty, the coalitional vectors system must exist for the game to be -balanced. Later, Hwang [ 3] treats the Cartesian product of these NTU games as a multiple-NTU game.
