Sur une généralisation des coefficients binomiaux
Abstract.
We prove a recent conjecture of Lassalle about positivity and
integrality of coefficients in some polynomial expansions.
We also give a combinatorial interpretation of those numbers.
Finally, we show that this question is closely related to the fundamental
problem of calculating the linearization coefficients for binomial coefficients.
