Abstract

We determine criteria for the prime spectrum of an ambiskew polynomial algebra RR over an algebraically closed field KK to be akin to those of two of the principal examples of such an algebra, namely the universal enveloping algebra U(sl2)U(sl_2) (in characteristic 00) and its quantization Uq(sl2)U_q(sl_2) (when qq is not a root of unity). More precisely, we aim to determine when the prime spectrum of RR consists of 00, the ideals (zλ)R(z-\lambda)R for some central element zz of RR and all λK\lambda\in K, and, for some positive integer dd and each positive integer mm, dd height two prime ideals with Goldie rank mm. New applications are to certain ambiskew polynomial rings over coordinate rings of quantum tori which arise, as localizations of connected quantized Weyl algebras.
