Abstract:
The author recently q-extended the approach of Qi, Wang, and Guo
to derangement numbers,
and successfully applied this extended approach to
obtain expressions for certain types B and D of
derangement polynomials as determinants of order n + 1.
In this paper,
we demonstrate that the q-extended approach is applicable to other generating functions, including the Eulerian polynomials
An(t),
Bn(t),
and
Dn(t)
for types A,B, and D, as well as the types
A and B "inv" analogues of q-Eulerian polynomials
Aninv(t, q)
and Bninv(t, q).
We also present a new recurrence relation for
Bninv(t, q).
