Empty set
In mathematics and more specifically set theory, the empty set is the unique set which contains no elements. In axiomatic set theory it is postulated to exist by the axiom of empty set. From it all finite sets are constructed. The empty set is also sometimes called the null set, but this terminology is rarely used in current work because of the conflict with the concept in the null set article.
