3.27 Stieltjes-Wigert

Definition.

 

Orthogonality.

 

Recurrence relation.

 

Normalized recurrence relation.

 

where

q-Difference equation.

 

Forward shift operator.

 

or equivalently

 

Backward shift operator.

 

or equivalently

 

where

Rodrigues-type formula.

 

Generating functions.

 

 

 

Remark. Since the Stieltjes and Hamburger moment problems corresponding to the Stieltjes-Wigert polynomials are indeterminate there exist many different weight functions. For instance, they are also orthogonal with respect to the weight function
