Regular algebras of dimension 4 with 3 generators (1101.1998v2)
Published 11 Jan 2011 in math.RA
Abstract: We study Artin-Schelter regular algebras of global dimension 4 with three generators of degree one. We classify those which are domains and which have an additional Z x Z-grading, and prove that all of these examples are also strongly noetherian, Auslander regular, and Cohen-Macaulay.
