Generic flatness and the nullstellensatz for ore extensions

Webextensions. The term ”Poisson-CGL extensions” is introduced by K. Goodearl and M. Yakimov in [20], and they are special examples of iterated Poisson-Ore extensions [25] with compatible torus actions. See §2 for more details. Prime ideals of Poisson-CGL extensions are studied by K. Goodearl and S. Launois in [14]. On the other hand, cluster WebRecently, S. Annin in [A1], [A2] extended this result to certain skew polynomial rings. In Section 5 we show that in many other situations all associated primes of the induced module M ›R S arise from associated primes of the module MR even in the case S is an iterated Ore extension of R.
