Module

Finitely generated module

An -module is said to be finitely generated iff it has a finite spanning set #m/def/module so that

Thus a vector space is finitely generate iff it is finite dimensional, however the situation is more complicated over a general ring.

Properties

  1. Let , . If and are finitely generated, then so too is .
Proof of 1.

Suppose and . Then
