初等子模型、编码策略和一个无限实数博弈

Elementary submodels, coding strategies, and an infinite real number game

Will Brian, Steven Clontz

摘要:

马修贝克调查,在以前的工作,一个优雅的,无限长的游戏,可用于研究子集的实数。我们提出了两个可访问的例子,如何从集合论的一个重要技术,或不同的技术从无限对策理论,可以用来回答贝克的问题,这个游戏是否提供了一个精确的表征可数子集的实数,我们连接这个游戏,从拓扑学研究的巴拿赫-马祖尔游戏。

英文摘要:

Matthew Baker investigated, in previous work, an elegant, infinite-length game that may be used to study subsets of real numbers. We present two accessible examples of how an important technique from set theory, or a different technique from infinite game theory, may be used to answer Baker's question on whether this game provides a precise characterization for countable subsets of real numbers, and we connect this game to the well-studied Banach-Mazur game from topology.
