选择与规则:逻辑中的常见结果

Choice and Regularity: Common Consequences in Logic

Denis I. Saveliev

摘要:

众所周知,选择性和正则性是相互独立的,但具有重要的共同逻辑特征(反射原则,集合表示类等)。我们解释这一现象,隔离他们的“交集”,一个原则(这里称为最佳基础),这是符合这两个公理的否定,但意味着所有这些后果。然后,我们详细研究这些后果(和近原则)之间的关系。最后,我们考虑了与集合论中各种原理的真值有关的一些争论,特别是关于可解释性强度的争论。

英文摘要:

It is well-known that Choice and Regularity are independent of each other but have important common consequences of logical character (reflection principles, representations of classes by sets, etc.). We explain this phenomenon by isolating their "intersection", a principle (called here Best-Foundedness) which is consistent with the negations of both axioms but implies all these consequences. Then we study relationships between these consequences (and near principles) in detail. Finally, we consider some arguments related to truth of various principles in set theory, especially arguments concerning the interpretability strength.
