allowing all its members to get the service that generates the revenues. We focus on the study of the core of cost … consideration to all its members, it is shown that a cost-revenue game has a non-empty core for any vector of revenues if, and only … if, the dual game of the cost game has a large core. Using this result, we investigate minimum cost spanning tree games …

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 …

In this paper we investigate some new applications of Scarf's Lemma. First, we introduce the notion of fractional core …

The appropriate extension of the classicakl core concept …, the Sustainable Core, is defined for this new setup to test the stability of allocations in such a complex environment.
