Abstract

The order of criticality of a player in a simple game and two indices inspired by the reasoning à la Shapley and à la Banzhaf were introduced in two previous papers [3] and [4], respectively, mainly having in mind voting situations. Here, we devote our attention to graph connection games, and to the computation of the order of criticality of a player. The indices introduced in [4] may be used as centrality measures of the edges in preserving the connection of a graph.

Notes

  1. 1.

    This property is called monotonicity.

  2. 2.

    In other terms, \(v(M \setminus T )=0\) or \(v(M \setminus (T \cup \{i\} ))=1\) for any \(T \subset M \setminus \{i\}\) with \(|T|< k\).
