Von Neumann universe — In 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… … Wikipedia
Von Neumann–Bernays–Gödel set theory — In the foundations of mathematics, von Neumann–Bernays–Gödel set theory (NBG) is an axiomatic set theory that is a conservative extension of the canonical axiomatic set theory ZFC. A statement in the language of ZFC is provable in NBG if and only … Wikipedia

Von Neumann cardinal assignment — The von Neumann cardinal assignment is a cardinal assignment which uses ordinal numbers. For a well ordered set U , we define its cardinal number to be the smallest ordinal number equinumerous to U . More precisely,:|U| = mathrm{card}(U) = inf {… … Wikipedia

Finite set — In mathematics, a set is called finite if there is a bijection between the set and some set of the form {1, 2, ..., n} where n is a natural number. (The value n = 0 is allowed; that is, the empty set is finite.) An infinite set is a set which is… … Wikipedia
Ordinal definable set — In mathematical set theory, a set S is said to be ordinal definable if, informally, it can be defined in terms of a finite number of ordinals by a first order formula. Ordinal definable sets were introduced by Gödel (1965). A drawback to this… … Wikipedia
Limit ordinal — A limit ordinal is an ordinal number which is neither zero nor a successor ordinal. Various equivalent ways to express this are: *It cannot be reached via the ordinal successor operation S ; in precise terms, we say lambda; is a limit ordinal if… … Wikipedia
