Abstract:
In this paper U-fields are characterized in terms of maximal subfields of their algebraic closures in case of a saturated class U of finite groups. A simple link between the maximal perfect subfield of a field and its purely inseparable closure is proved to exist. The q-maximal problem is considered in detail.
