n_{m}] = ᴨ^{m}_{i=1}(1-q^{n-m+i})/(1-q^{i}), for integers 0≤m≤n, are known to be polynomials with non-negative integer coefficients. This readily follows from the q-binomial theorem, or the many combinatorial interpretations of [^{n}_{m}]. In this note we conjecture an arithmetically motivated generalisation of the non-negativity property for products of ratios of q-factorials that happen to be polynomials.]]>Tue 03 Feb 2015 10:09:42 EST]]>
