Affine q-Krawtchouk.
Affine q-Krawtchouk.
The affine q-Krawtchouk polynomials defined by (3.16.1)
can be obtained from the q-Hahn polynomials by the substitution 
and
in (3.6.1) :
Affine q-Krawtchouk.
The affine q-Krawtchouk polynomials defined by (3.16.1)
can be obtained from the dual q-Hahn polynomials by the substitution 
and 
in (3.7.1) :
Note that 
in this case.
Little q-Laguerre / Wall.
If we set 
in the definition (3.16.1)
of the affine q-Krawtchouk polynomials and take the limit
we simply obtain the little q-Laguerre (or Wall)
polynomials defined by (3.20.1) :
