See all on Wikipediahttps://en.wikipedia.org/wiki/Empty_setIn 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, while in other theories, its existence can be deduced. Many possible properties of sets … See more
Common notations for the empty set include "{}", "", and "∅". The latter two symbols were introduced by the Bourbaki group (specifically André Weil) in 1939, inspired by the letter Ø in the Danish and Norwegian alphabets. … See more
In standard axiomatic set theory, by the principle of extensionality, two sets are equal if they have the same elements. As a result, there can be only one set with no elements, hence the … See more

Emptyset is a Bristol-based production project, formed in 2005 by James Ginzburg and Paul Purgas. Ginzburg and Purgas say that by working across performance, installation and the moving image they are examining the physical properties of sound, the legacy of analogue media reflecting upon structural/materialist art production and the perceptual boundaries between n…

- In axiomatic set theory, the axiom of empty set is a statement that asserts the existence of a set with no elements. It is an axiom of Kripke–Platek set theory and the variant of general set theory that Burgess calls "ST," and a demonstrable truth in Zermelo set theory and Zermelo–Fraenkel set theory, with or without the axiom of choice.
