For totally positive games this solution is always contained in the 'Core', and contains the well … coalitions). For special orderings it equals the Core, respectively Shapley value.

We consider cooperative games with transferable utility (TU-games), in which we allow for a social structure on the set … of players. The social structure is utilized to refine the core of the game. For every coalition the relative strength of … stable core is the set of socially stable elements of the core. We show that the socially stable core is non-empty if the …

In case of …

In this paper we provide three new characterizations of largeness of the core. The first characterization of largeness … of the core is based on minimal covers of the grand coalition and associated inequalities. The second characterization … shows the relation between the bases that provide core elements of the game and the bases that provide core elements of the …
