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 ..

Some Basic Group Theory,r that are unlikely to appear in first group theory courses. In the main we use them only once or perhaps twice in the latter half of the book, so readers might like to put off reading them until they actually need them. We present full proofs of these results.
