Abstract
Let be three positive integers. We prove that the rational fractions of : are polynomials of with positive integer coefficients. This generalizes a recent result of Lassalle (Ann. Comb. 6(2002), no. 3-4, 399-405), in the same way as the classical -binomial coefficients refine the ordinary binomial coefficients.
