阶级理论中的阶级强迫

Class-Forcing in Class Theory

Carolin Antos

摘要:

在这篇文章中,我们调整现有的帐户类强迫ZFC模型的模型$(M,\mathcal{C})$的Morse-Kelley类理论。我们给出了一个严格的定义,在这样一个模型中的类强迫,并表明,可定义性引理(和真理引理)可以证明,而不限制强迫的概念。此外,我们显示在何种条件下的公理被保存。最后,我们证明拉沃尔定理不适用于类强迫。

英文摘要:

In this article we adapt the existing account of class-forcing over a ZFC model to a model $(M,\mathcal{C})$ of Morse-Kelley class theory. We give a rigorous definition of class-forcing in such a model and show that the Definability Lemma (and the Truth Lemma) can be proven without restricting the notion of forcing. Furthermore we show under which conditions the axioms are preserved. We conclude by proving that Laver's Theorem does not hold for class-forcings.
