§18.25 Wilson Class: Definitions
The Wilson class consists of two discrete families (Racah and dual Hahn) and two continuous families (Wilson and continuous dual Hahn). Table 18.25.1 lists the transformations of variable, orthogonality ranges, and parameter constraints that are needed in §18.2(i) for the Wilson polynomials W n ( x ; a , b , c , d ) , continuous dual Hahn polynomials S n ( x ; a , b , c ) , Racah polynomials R n ( x ; α , β , γ , δ ) , and dual Hahn polynomials R n ( x ; γ , δ , N ) . … Under certain conditions on their parameters the orthogonality range for the Wilson polynomials and continuous dual Hahn polynomials is ( 0 , ) S , where S is a specific finite set, e. …
