Wikipedia a dit:By the principle of extensionality, two sets are equal if they have the same elements; therefore there can be only one set with no elements. Hence there is but one empty set, and we speak of "the empty set" rather than "an empty set."
Wikipedia a dit:By the definition of subset, the empty set is a subset of any set A, as every element x of ? belongs to A. If it is not true that every element of ? is in A, there must be at least one element of ? that is not present in A. Since there are no elements of ? at all, there is no element of ? that is not in A. Hence every element of ? is in A, and ? is a subset of A. Any statement that begins "for every element of ?" is not making any substantive claim; it is a vacuous truth. This is often paraphrased as "everything is true of the elements of the empty set."
