In mathematics, a surjective function is a function f such that every element y can be mapped from element x so that f(x) = y. In other words, every element of the function's codomain is the image of at least one element of its domain. It is not required that x be unique; the function f may map one or more … Ver mais • For any set X, the identity function idX on X is surjective. • The function f : Z → {0, 1} defined by f(n) = n mod 2 (that is, even integers are mapped to 0 and odd integers to 1) is surjective. Ver mais • Bijection, injection and surjection • Cover (algebra) • Covering map • Enumeration • Fiber bundle Ver mais A function is bijective if and only if it is both surjective and injective. If (as is often done) a function is identified with its graph, then surjectivity is not a property of the … Ver mais Given fixed A and B, one can form the set of surjections A ↠ B.

Two sets A and B are equal if and only if A ⊂ B and B ⊂ A. If A ⊂ B and A does not equal B, we say that A is a proper subset of B, and write A ⊊ B. The set θ = {x: x ≠ x} is called the empty set. This set clearly has no elements. Using Theorem 1.1.1, it is easy to show that all sets with no elements are equal.
