In mathematics, the empty set is the unique set having no elements; its size or cardinality is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set, while in other theories, its existence can be deduced.
In mathematics, the empty set, also known as the null set or the void set, is a set with no elements. It is denoted by the symbol {} or ∅. The empty set is unique, and any set that has no elements is considered to be the empty set. It is often used in set theory, algebra, and other branches of mathematics to represent the absence of a solution or the lack of an element in a set.
