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 Ver mais A function is bijective if and only if it is both surjective and injective.

That is, a function : is open if for any open set in , the image is open in . Likewise, a closed map is a function that maps closed sets to closed sets. A map may be open, closed, both, or neither; in particular, an open …

The former has equal spacing on each side (it's a \mathrel, I think), while the latter has greater spacing on the right. That is, f : A \to B renders as "f : A → B," while f \colon A \to B renders as "f: A → B."
