in the definition (3.21.1)
of the q-Laguerre polynomials and take the limit 
we obtain
the Laguerre polynomials given by (1.11.1) :
If we set in the definition (3.21.1)
of the q-Laguerre polynomials and take the limit we obtain
the Laguerre polynomials given by (1.11.1) :
If we set 
and 
(or
) in the definition (3.21.1) of the
q-Laguerre polynomials, multiply by 
, and take the limit
we obtain the Charlier polynomials given by (1.12.1) :
