We study the stability and the stability index of the meet game form defined on a meet semilattice. Given any active coalition structure, we show that the stability index relative to the equilibrium, to the beta core and to the exact core is a function of the Nakamura number, the depth of the...

Let Gm,n be the class of strategic games with n players, where each player has m\geq2 pure strategies. We are interested in the structure of the set of correlated equilibria of games in Gm,n when n -\infty. As the number of equilibrium constraints grows slower than the number of pure strategy...
