Terrorism from Above and Below,.? How long can a chain of prime ideals of .. be? These are the sort of questions we consider in this chapter. The proofs frequently use induction on the Hirsch number, so we begin by looking at the connection between the prime ideals of .. and the prime ideals of .. for . a normal subgroup of ..

Hypercentral Groups and Rings,group ring ... Our main aim is to prove Roseblade’s theorems that .. is a hypercentral ring if and only if . is a hypercentral group and that .. is a polycentral ring if and only if . is a finitely generated nilpotent group. We must start by explaining these terms.
