Groups with finitely many normalizers of non-subnormal subgroups
Abstract
It is proved that a group G has finitely many normalizers of non-subnormal subgroups if and only if each subgroup of G either is subnormal or has finitely many conjugates; groups with this latter property have been completely described in [8]. Moreover, groups with finitely many normalizers of infinite non-subnormal subgroups are described.The authors retain all rights to the original work without any restrictions.
