costs be shared among the agents. Ni and Wang (2007) first consider this problem as cost sharing problems on a river network …

derived from this participation. In fact, this new set or network structure unifies and generalizes well-known models from the … literature, such as communication networks and hierarchies. We introduce and analyze accessible union stable systems where union … stability reflects the communication network and accessibility describes the hierarchy. Particular cases of these new structures …

A symmetric network consists of a set of positions and a set of bilateral links between these positions. Examples of … such networks are exchange networks, communication networks, disease transmission networks, control networks etc. For every … symmetric network we define a cooperative transferable utility game that measures the power of each coalition of positions in …

which they usually take different positions. Two examples of such structures are communication networks and hierarchies. In … feasible sets in communication networks and compare them with feasible sets arising from hierarchies. …

able to cooperate only if they can form a network in the graph. A single-valued solution, the average tree solution, is …
