The Axiom of the Empty Set is a fundamental concept in set theory, which states that there exists a set that contains no elements. This set is called the empty set, denoted by the symbol ∅ or \{\}. Formally, the Axiom of the Empty Set asserts: There exists a set \\( \\emptyset \\) such that for any element \\( x \\), \\( x \\notin \\emptyset \\).
