bijective function
1Bijective proof — In combinatorics, bijective proof is a proof technique that finds a bijective function f : A → B between two sets A and B , thus proving that they have the same number of elements, | A | = | B |. One place the technique is useful is where we wish …

7Surjective function — Onto redirects here. For other uses, see wikt:onto. A surjective function from domain X to codomain Y. The function is surjective because every point in the codomain is the value of f(x) for at least one point x in the domain. In mathematics, a… …
8Inverse function — In mathematics, if fnof; is a function from A to B then an inverse function for fnof; is a function in the opposite direction, from B to A , with the property that a round trip (a composition) from A to B to A (or from B to A to B ) returns each… …
