# Category:Algebraic Functions

This category contains results about Algebraic Functions.
Definitions specific to this category can be found in Definitions/Algebraic Functions.

### Real Algebraic Function

Let $y$ be a solution to the polynomial equation:

$\map {p_0} x + \map {p_1} x y + \dotsb + \map {p_{n - 1} } x y^{n - 1} + \map {p_n} x y^n = 0$

where $\map {p_0} x \ne 0, \map {p_1} x, \dotsc, \map {p_n} x$ are real polynomial functions in $x$.

Then $y = \map f x$ is a (real) algebraic function:

### Complex Algebraic Function

Let $w$ be a solution to the polynomial equation:

$\map {p_0} z + \map {p_1} z w + \dotsb + \map {p_{n - 1} } z w^{n - 1} + \map {p_n} z w^n = 0$

where $\map {p_0} z \ne 0, \map {p_1} z, \dotsc, \map {p_n} z$ are complex polynomial functions in $z$.

Then $w = \map f z$ is a (complex) algebraic function:
