Hypergeometric 2F0
From specialfunctionswiki
The hypergeometric ${}_2F_0$ is defined by $${}_2F_0(a,b;;z)=\displaystyle\sum_{k=0}^{\infty} \dfrac{(a)_k(b)_k z^k}{k!},$$ where $(a)_k$ denotes the Pochhammer symbol and $k!$ denotes the factorial.
Properties
Bessel polynomial generalized hypergeometric
