List of mathematical functions
In mathematics, some functions or groups of functions are important enough to deserve their own names. This is a listing of articles which explain some
Membership function (mathematics)
in mathematics. One application of membership functions is as capacities in decision theory. In decision theory, a capacity is defined as a function, ν
Partial function
In mathematics, a partial function from X to Y (sometimes written as f : X ↛ Y, f: X ⇸ Y, or f: X ↪ Y)[citation needed] is a function f: X′ → Y, for some
Surjective function

Function composition
In mathematics, function composition is an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x)). In this operation
Bijection
In mathematics, a bijection, bijective function, or one-to-one correspondence is a function between the elements of two sets, where each element of one
Monotonic function
In mathematics, a monotonic function (or monotone function) is a function between ordered sets that preserves or reverses the given order. This concept
Domain of a function
In mathematics, the domain of definition (or simply the domain) of a function is the set of "input" or argument values for which the function is defined
