Gaussian Hypergeometric Function
The Gaussian hypergeometric function is an instance of a generalized hypergeometric function, given for $\size z < 1$ by:
\(\ds \map F {a, b; c; z}\) | \(:=\) | \(\ds \sum_{n \mathop = 0}^\infty \dfrac {a^{\overline n} b^{\overline n} } {c^{\overline n} } \dfrac {z^n} {n!}\) | where $x^{\overline n}$ denotes the $n$th rising factorial power of $z$ | |||||||||||
\(\ds \) | \(=\) | \(\ds 1 + \dfrac {a b} {1! \, c} z + \dfrac {a \paren {a + 1} b \paren {b + 1} } {2! \, c \paren {c + 1} } z^2 + \dfrac {a \paren {a + 1} \paren {a + 2} b \paren {b + 1} \paren {b + 2} } {3! \, c \paren {c + 1} \paren {c + 2} } z^3 + \cdots\) |
Generalized Hypergeometric Function
A generalized hypergeometric function is a function which can be defined in the form of a hypergeometric series defined as:
- $\ds \map { {}_m \operatorname F_n} { { {a_1, \ldots, a_m} \atop {b_1, \ldots, b_n} } \, \middle \vert \, z} = \sum_{k \mathop = 0}^\infty \dfrac { {a_1}^{\overline k} \cdots {a_m}^{\overline k} } { {b_1}^{\overline k} \cdots {b_n}^{\overline k} } \dfrac {z^k} {k!}$
where $x^{\overline k}$ denotes the $k$th rising factorial power of $x$.
