Buchsbaum ring
From Wikipedia, the free encyclopedia
In mathematics, Buchsbaum rings are Noetherian local rings such that every system of parameters is a weak sequence. A sequence of the maximal ideal is called a weak sequence if for all .
They were introduced by Jürgen Stückrad and Wolfgang Vogel (1973) and are named after David Buchsbaum.
Every Cohen–Macaulay local ring is a Buchsbaum ring. Every Buchsbaum ring is a generalized Cohen–Macaulay ring.
