Axiomatic set theory In Zermelo set theory, the existence of the empty set is assured by the axiom of empty set, and its uniqueness follows from the axiom of extensionality. However, the axiom of empty set can be shown redundant in at least two ways: Standard first-order logic implies, merely from the … See more In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set, … See more In standard axiomatic set theory, by the principle of extensionality, two sets are equal if they have the same elements.

I know the three axioms, but I fail to employ these axioms to prove the above. I understand it only intuitively but would like a more formal explanation. 1 = P ( Ω) = P ( Ω ∪ ∅) = P ( Ω) + P ( ∅) implies P ( ∅) = 0 because ...
