博弈论中的不动点定理及其应用

Fixed Point Theorems and applications in Theory of Games

Monica Patriche

摘要:

引入弱 *-凹对应和弱自然拟凹对应的概念,证明了这类对应的不动点定理和连续选择定理.作为对策论的应用,利用基于连续选择的技术,建立了抽象经济均衡的新的存在性结果.约束对应是弱自然拟凹的。我们证明了在没有连续性假设的情况下均衡的存在。

英文摘要:

We introduce the notions of weakly *-concave and weakly naturally quasi-concave correspondence and prove fixed point theorems and continuous selection theorems for these kind of correspondences. As applications in the game theory, by using a tehnique based on a continuous selection, we establish new existence results for the equilibrium of the abstract economies. The constraint correspondences are weakly naturally quasi-concave. We show that the equilibrium exists without continuity assumptions.
