In this paper we characterize the class of games for which the core coincides with the core cover (compromise stable games). Moreover we will develop an easy explicit formula for the nucleolus for this class of games, using an approach based on bankruptcy problems. Also the class of convex compromise stable games is characterized. The relation between core(More)
The τ-measure is introduces as a method to rank the nodes in a digraph competition. It coincides with the τ-value of an associated transferable utility game, the so-called digraph game. The τ-measure is characterized in two ways. One of them is based on a characterization of the τ-value in bankruptcy games and uses a decomposition axiom. This(More)
