我们研究了非平凡初等嵌入的概念,假设V满足ZFC没有权力集,但收集计划。我们表明,没有这样的嵌入可以存在下的额外的假设,它是共尾的,无论是一个集合或方案的依赖选择的任意长度举行。然后,我们研究失败的集合的实例在对称子模型的类强迫。
We study the notion of non-trivial elementary embeddings under the assumption that V satisfies ZFC without Power Set but with the Collection Scheme. We show that no such embedding can exist under the additional assumption that it is cofinal and either is a set or that the scheme of Dependent Choices of arbitrary length holds. We then study failures of instances of Collection in symmetric submodels of class forcings.
