广义超几何函数
广义超几何函数(generalized hypergeometric function),有时也称超几何函数,是一个用幂级数定义的函数,其中幂级数的系数由若干个升阶乘的积和商给出。下文中用“超几何函数”一词代指广义超几何函数,而用“高斯超几何函数”一词代指 p=2, q=1 时的广义超几何函数。

Generalized hypergeometric function 广义超几何函数In mathematics, a generalized hypergeometric series is a power series in which the ratio of successive coefficients indexed by n is a rational function of n. The series, if convergent, defines a generalized hypergeometric function, which may then be defined over a wider domain of the argument by analytic continuation. The generalized hypergeometric series is sometimes just called the hypergeometric series, though this term also sometimes just refers to the Gaussian hypergeometric series. Generalized hypergeometric functions include the (Gaussian) hypergeometric function and the confluent hypergeometric function as special cases, which in turn have many particular special functions as special cases, such as elementary functions, Bessel functions, and the classical orthogonal polynomials. |
