Modules of Finite Type
We introduced and defined rings and modules of finite type in Section 8.1, but then the rest of Chapter 8 was devoted to studying modules of type ≤ 2. (Auslander– Bridger modules and dual Auslander–Bridger modules do not have type ≤ 2 in general, but they do have semilocal endomorphism rings.) In this chapter we will see some further results on modules of finite arbitrary type.
