摘要：The (generalized) extremal algebra [4] is Noetherian, Auslander regular and Cohen-Macaulay. A necessary and sufficient condition is given for the generalized extremal algebras being Calabi-Yau. The point modules over these algebras are described explicitly. (C) 2014 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
