Английская Википедия:Generalized Pochhammer symbol
Материал из Онлайн справочника
In mathematics, the generalized Pochhammer symbol of parameter <math>\alpha>0</math> and partition <math>\kappa=(\kappa_1,\kappa_2,\ldots,\kappa_m)</math> generalizes the classical Pochhammer symbol, named after Leo August Pochhammer, and is defined as
- <math>(a)^{(\alpha )}_\kappa=\prod_{i=1}^m \prod_{j=1}^{\kappa_i}
\left(a-\frac{i-1}{\alpha}+j-1\right). </math> It is used in multivariate analysis.
