   What is an example of an uncountable Union?

   • The formulations "union of a countable sequence of sets" and "union of a countable set of sets" are equivalent provided we have the axiom of choice. In addition to the other answers, here is an example of an uncountable union: Say that Ax = (0, x) A x = (0, x) for every x ∈ R+ x ∈ R +. ⋃x∈R+Ax ⋃ x ∈ R + A x is an uncountable union.

   Which axiom is a finite/countable union of foobar sets?

   • By the Axiom of Union (in ZFC), if A A is a set, then there is a set ⋃ A ⋃ A that is characterized by x ∈ ⋃ A ⟺ ∃z ∈ A: x ∈ z x ∈ ⋃ A ⟺ ∃ z ∈ A: x ∈ z. We say " X X is a finite/countable union of foobar sets" if there exists a finite/countable set A A such that all elements of A A are foobar sets and X = ⋃ A X = ⋃ A.

   It is a set of the form ∪I ∈ SI where S is a countable set whose elements are open intervals. We usually write ∪k ∈ NIk, where Ik is a sequence of intervals. The formulations "union of a countable sequence of sets" and "union of a countable set of sets" are equivalent provided we have the axiom of choice. Share. Cite.
