Abstract

In this paper, we provide an effective characterization of all the subgame-perfect equilibria in infinite duration games played on finite graphs with mean-payoff objectives. To this end, we introduce the notion of requirement, and the notion of negotiation function. We establish that the plays that are supported by SPEs are exactly those that are consistent with a fixed point of the negotiation function. Finally, we use that characterization to prove that the SPE threshold problem, who status was left open in the literature, is decidable.

平均收益博弈中的次级完美均衡(期刊版)

在本文中，我们提供了有限图上具有平均收益目标的无限持续博弈的所有子博弈-完美均衡的有效表征。为此，我们引入了需求的概念和协商函数的概念。我们确定spe所支持的玩法正是那些与协商功能的固定点相一致的玩法。最后，我们使用该表征来证明SPE阈值问题是可确定的，谁的状态在文献中是开放的。
