Definition:Hypergeometric Function/Gaussian

Definition
The Gaussian hypergeometric function is an instance of a generalized hypergeometric function, given for $\size z < 1$ by:

Also denoted as
Using the notation of the generalized hypergeometric function, the Gaussian hypergeometric function can be denoted as:


 * $\ds \map { {}_2 F_1} {a, b; c; z}$

or if necessary to draw particular attention to where it came from:


 * $\ds \map { {}_2 F_1} { { {a, b} \atop c} \, \middle \vert \, z}$

Also known as
The Gaussian hypergeometric function is also known as the ordinary hypergeometric function, or just the hypergeometric function

Some sources refer to this as Gauss's hypergeometric function or (grammatically inaccurately) Gauss' hypergeometric function.
