We investigate the algebra Fq(N) introduced by Faddeev, Reshetikhin and Takhadjian [3]. In case q is a primitive root of unity the degree, the center, and the set of irreducible representations are found. The Poisson structure is determined and the De Concini-Kac-Procesi Conjecture is proved for this case. In the case of q generic, the primitive ideals are… (More)
