The core cover of a TU-game is a superset of the core and equals the convex hull of its larginal vectors. A larginal … called compromise stable if the core is equal to the core cover, i.e. the core is the convex hull of the larginal vectors. In … larginal vector of the set is a core element, then the game is compromise stable. The first characterization of these sets is …

We generalize the characterizations of the positive core and the positive prekernel to TU games with precedence … constraints and show that the positive core is characterized by non-emptiness (NE), boundedness (BOUND), covariance under … generalized Davis-Maschler reduced games, and the possibility of nondiscrimination. The bounded positive core, i.e., the union of …

It is well-known that the core on several domains of cooperative transferable utility (TU) and nontransferable utility … is shown that, if communication structures are present, the core may still be characterized on balanced TU games, on … totally balanced TU games, on NTU games with a nonempty core, on the domains of all TU or NTU games, and on several other …

This paper considers situations characterized by a common-pool resource, which needs to be divided among agents. Each of the agents has some claim on this pool and an individual reward function for assigned resources. This paper analyzes not only the problem of maximizing the total joint reward,...

If the excesses of the coalitions in a transferable utility game are weighted, then we show that the arising weighted modifications of the well-known (pre)nucleolus and (pre)kernel satisfy the equal treatment property if and only if the weight system is symmetric in the sense that the weight of...

Furthermore we show that core stability is equivalent to essential … extendibility. We also obtain that largeness of the core as well as extendibility and exactness of the game are equivalent …
