Abstract: Down-up algebras $A= A(\alpha ,\beta ,\gamma )$ were introduced by G. Benkart and T. Roby to better understand the structure of certain posets. In this paper, we prove that $\beta \neq 0$ is equivalent to $A$ being right (or left) Noetherian, and also to $A$ being a domain. Furthermore, when this occurs, we show that $A$ is Auslander-regular and has global dimension 3.
