摘要：In this paper, we provide some conditions under which zero-sum average payoff stochastic games with a Borel state space have a value and the players possess optimal stationary strategies. One contains as special cases various ergodicity assumptions considered recently in the theory of Markov decision processes. We also consider games with state independent transition probabilities.

摘要：Various sufficient conditions are given for a noncooperative game to have a Nash equilibrium. One hypothesis used is that of limiting the variables that a player's payoff function depends on-this allows a weakening of the hypotheses imposed on the choice sets. Other conditions allow convexity to be dropped or replaced by contractibility. Approximate equilibrium results are given with some noncompactness of choice sets. The methods used for obtaining the equilibria are used to discuss the price...

摘要：The topic of the presentation is the determination of exact bounds for the nonempty core of a cooperative game in characteristic function form. The exact lower and upper core bounds are determined in terms of the extremal excesses with respect to reduced upper and lower coverings. (C) 1994 Academic Press, Inc.
