Abstract: | For the quantum integer n]q=1+q+q2+?+qn−1 there is a natural polynomial multiplication such that m]q⊗qn]q=mn]q. This multiplication leads to the functional equation fm(q)fn(qm)=fmn(q), defined on a given sequence of polynomials. This paper contains various results concerning the construction and classification of polynomial sequences that satisfy the functional equation, as well open problems that arise from the functional equation. |
