Weight modules over Bell--Rogalski algebras

Rings and Algebras 2023-09-25 v2

Abstract

We study a class of Z\mathbb{Z}-graded algebras introduced by Bell and Rogalski. Their construction generalizes in large part that of rank one generalized Weyl algebras (GWAs). We establish certain ring-theoretic properties of these algebras and study their connection to GWAs. We classify the simple weight modules in the infinite orbit case and provide a partial classification in the case of orbits of finite order.
