5.20 Little q-Laguerre / Wall --> Laguerre / Charlier

Little q-Laguerre / Wall --> Laguerre

If we set and in the definition (3.20.1) of the little q-Laguerre (or Wall) polynomials and let q tend to one, we obtain the Laguerre polynomials given by (1.11.1) :

Little q-Laguerre / Wall --> Charlier

If we set and in the definition (3.20.1) of the little q-Laguerre (or Wall) polynomials and take the limit we obtain the Charlier polynomials given by (1.12.1) in the following way :
