# Noetherian module

A module for which every submodule has a finite system of generators. Equivalent conditions are: the ascending chain condition for submodules (every strictly ascending chain of submodules breaks off after finitely many terms); every non-empty set of submodules ordered by inclusion contains a maximal element. Submodules and quotient modules of a Noetherian module are Noetherian. If, in an exact sequence

$$0\to M'\to M\to M''\to0,$$

$M'$ and $M''$ are Noetherian, then so is $M$. A module over a Noetherian ring is Noetherian if and only if it is finitely generated. A module has a composition series if and only if it is both Artinian and Noetherian.
