notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we … will present a general mathematical programming algorithm which can be applied to find an element in the interval core. As … demonstrate how interval core elements can be computed. Also, we reveal that pitfalls exist if interval core elements are computed …

utility (TU) game from the viewpoint of general equilibrium theory. For any given game, we construct a competitive exchange … coalition production economy corresponding to the game. First, it is shown that the full core of a TU game is not empty if and … only if the completion of the game is balanced. The full core is defined free of any particular coalition structure and the …

We are concerned with the problem of core membership testing for hedonic coalition formation games, which is to decide … whether a certain coalition structure belongs to the core of a given game. We show that this problem is co-NP complete when …

We show that this equivalence holds only in an atomless … economy by giving two examples of the sequence of replica economies such that in any replica economy, there exists a core …
