Title: Power indices: a measure of centrality in networks
Abstract: A cooperative game describes a situation in which all players can freely interact with each other, i.e. all coalitions are feasible. However, this is not the case in many real world situations. A typical situation is when the restriction of communication possibilities between players is modelled by a network. In this scenario power indices have been used to evaluate the centrality of nodes (the players of the cooperative game). In the talk, an overview of solution concepts for cooperative games with restricted communications will be provided and applications to centrality analysis in social and biological networks will be discussed.
