## Definition

### Symbol-free definition

A group is said to be **Noetherian** or **slender** or to satisfy the **maximum condition on subgroups** if it satisfies the following equivalent conditions:

- Every subgroup is finitely generated
- Any ascending chain of subgroups stabilizes after a finite length.
- Any nonempty collection of subgroups has a maximal element: a member of that collection that is not contained in any other member of the collection.

## Formalisms

### In terms of the hereditarily operator

This property is obtained by applying the hereditarily operator to the property: finitely generated group

## Metaproperties

Metaproperty name | Satisfied? | Proof | Statement with symbols |
---|---|---|---|

subgroup-closed group property | Yes | Noetherianness is subgroup-closed | If is a Noetherian group and is a subgroup, then is Noetherian. |

quotient-closed group property | Yes | Noetherianness is quotient-closed | If is a Noetherian group and is a normal subgroup, the quotient group is Noetherian. |

extension-closed group property | Yes | Noetherianness is extension-closed | If is a normal subgroup of such that both and are Noetherian, then is also Noetherian. |
