In mathematics, Wilson polynomials are a family of orthogonal polynomials introduced by that generalize Jacobi polynomials, Hahn polynomials, and Charlier polynomials.
They are defined in terms of the generalized hypergeometric function and the Pochhammer symbols by
| 2)=(a+b) | |
| p | |
| n(a+c) |
n(a+d)n{}4F3\left(\begin{matrix}-n&a+b+c+d+n-1&a-t&a+t\ a+b&a+c&a+d\end{matrix};1\right).
