A symmetric network consists of a set of positions and a set of bilateral links between these positions. Examples of … symmetric network we define a cooperative transferable utility game that measures the power of each coalition of positions in … the network. Applying the Shapley value to this game yields a network power measure, the beta-measure, which reflects the …
