Un q-analogue des polynômes de Bessel
Abstract.
The combinatorial model for the Bessel polynomials, introduced by
Dulucq and Favreau [IMACS Ann. Comput. Appl. Math. 9 (1991), 243-249],
allows us to define the q-Bessel polynomials. This model,
based upon weighted involutions, leads to a combinatorial interpretation
of the three-term recurrence relation and to an explicit formula
for the n-th q-Bessel polynomial.
