二变量逻辑小模型性质的一种简单组合证明

A simple combinatorial proof for small model property of two-variable logic

Yanger Ma, Tony Tan

摘要:

给出了二变量逻辑的{ \em小模型性质}的另一个证明。据我们所知,现有的证明这一性质严重依赖于模型理论的概念。相比之下,我们的是纯粹的组合,只使用了一个非常简单的计数参数,我们发现这是相当直观和优雅的。

英文摘要:

We present another proof for the well-known {\em small model property} of two-variable logic. As far as we know, existing proofs of this property rely heavily on model theoretic concepts. In contrast, ours is purely combinatorial and uses only a very simple counting argument, which we find rather intuitive and elegant.
