Definition
Symbol-free definition
A group is said to satisfy the normalizer condition, if it satisfies the following equivalent conditions:
- The normalizer of any proper subgroup properly contains it
- There is no proper self-normalizing subgroup
- Every subgroup is ascendant
Definition with symbols
A group is said to satisfy a normalizer condition if for any proper subgroup of , with the inclusion being strict (that is, is properly contained in its normalizer).
Groups satisfying the normalizer condition have been termed N-groups but the term N-group is also used for groups with a particular condition on normalizers of solvable subgroups.
Relation with other properties
Stronger properties
- Nilpotent group: It turns out that for a finitely generated group, the two properties are equivalent. For proof of the implication, refer Nilpotent implies normalizer condition and for proof of its strictness (i.e. the reverse implication being false) refer Normalizer condition not implies nilpotent.
