In axiomatic set theory, the axiom of union is one of the axioms of Zermelo–Fraenkel set theory. This axiom was introduced by Ernst Zermelo. The axiom states that for each set x there is a set y whose elements are precisely the elements of the elements of x. See more In the formal language of the Zermelo–Fraenkel axioms, the axiom reads: $${\displaystyle \forall A\,\exists B\,\forall c\,(c\in B\iff \exists D\,(c\in D\land D\in A)\,)}$$ See more In the context of set theories which include the axiom of separation, the axiom of union is sometimes stated in a weaker form which only … See more • Paul Halmos, Naive set theory.
