This paper contains some characterizations of normal Fitting classes. Let ℱ be a Fitting class of finite soluble groups. It is proved that ℱ is a normal Fitting class if and only if every ℱ-dualpronormal subgroup has respectively one of the following embedding properties: normal, subnormal, pronormal, normal embedded.

Abstract
This paper contains some characterizations of normal Fitting classes. Let ℱ be a Fitting class of finite soluble groups. It is proved that ℱ is a normal Fitting class if and only if every ℱ-dualpronormal subgroup has respectively one of the following embedding properties: normal, subnormal, pronormal, normal embedded.File in questo prodotto:
