Buchsbaum ring

In mathematics, Buchsbaum rings are Noetherian local rings such that every system of parameters is a weak sequence. A sequence (a1,⋯,ar) of the maximal ideal m is called a weak sequence if m⋅((a1,⋯,ai−1):ai)⊂(a1,⋯,ai−1) for all i.

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.
