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 and are named after David Buchsbaum.
Every CohenâÂÂMacaulay local ring is a Buchsbaum ring. Every Buchsbaum ring is a generalized CohenâÂÂMacaulay ring.
