连续逻辑中类型空间的拓扑刻画

Topometric characterization of type spaces in continuous logic

James Hanson

摘要:

我们证明了拓扑度量空间$X$拓扑同构于某个连续一阶理论的型空间当且仅当$X$是紧的并且有开度量(即,满足$\{p : d(p,U) < \varepsilon\}$对于每个打开的$U$和$\varepsilon > 0$是打开的)。此外,我们表明,这总是可以实现一个稳定的理论。

英文摘要:

We show that a topometric space $X$ is topometrically isomorphic to a type space of some continuous first-order theory if and only if $X$ is compact and has an open metric (i.e., satisfies that $\{p : d(p,U) < \varepsilon\}$ is open for every open $U$ and $\varepsilon > 0$). Furthermore, we show that this can always be accomplished with a stable theory.
