WebIn fact, one cannot prove that any infinite set exists: the hereditarily-finite sets constitute a model of ZF without Infinity. This bothers me quite a bit for the following reason.

"Web22 de jun. de 2015 · Since each Box Set is countably infinite (Aleph Null), and the real numbers on the unit interval are not countably infinite (at least Aleph One), there must be a set of the real numbers which will never be contained in any Box Set N as N goes to infinity. We may call that set the "unboxables". Question 2: What is the "unboxable" set? " - Hierarchy of infinite number sets

WebA natural number can be used to express the size of a finite set; more precisely, a cardinal number is a measure for the size of a set, which is even suitable for infinite sets. This concept of "size" relies on maps between sets, such that two sets have the same size , exactly if there exists a bijection between them. is the cardinality of the set of all countable ordinal numbers, called or sometimes . This is itself an ordinal number larger than all countable ones, so it is an uncountable set. Therefore, is distinct from . The definition of implies (in ZF, Zermelo–Fraenkel set theory without the axiom of choice) that no cardinal number is between and . If the axiom of choice is used, it can be further proved that the class of cardinal numbers is totally ordered, and thus is the second-smallest infinite cardinal num…

WebIn particular, in ZFC using the Replacement axiom in the form of transfinite recursion, there are huge uncountable sets of different infinite cardinalities. The infinities ℵα, for example, are defined by transfinite recursion: ℵ0 is the first infinite cardinality, or ω. ℵα + 1 is the next (well-ordered) cardinal after ℵα. Web26 de set. de 2016 · All ZFC sets are in the von Neumann hierarchy. And the reason for that is exactly the axiom of foundation. Basically large sets are large because they have many elements, and therefore also many chains, not because they have long chains. The length of each chain is finite. The number of chains can be arbitrarily large. Share Cite …
