Groups all of whose infinite abelian pd-subgroups are normal
The author studies groups in which any infinite Abelian pd-subgroup (p is a prime) is normal, on the assumption that the group indeed contains such subgroups (IHp-groups). Necessary and sufficient conditions are established for a group to be an IHp-group. Relationships are established between the class of IHp-groups and the class of groups in which all infinite Abelian subgroups are normal, and the class of groups in which all pd-subgroups are normal.
