フォン・ノイマン宇宙
1. Von Neumann universeIn set theory and related branches of mathematics, the von Neumann universe, or von Neumann hierarchy of sets, denoted V, is the class of hereditary well-founded sets. This collection, which is formalized by Zermelo–Fraenkel set theory (ZFC), is often used to provide an interpretation or motivation of the axioms of ZFC. The rank of a well-founded set is defined inductively as the smallest ordinal number greater than the ranks of all members of the set.
