Sull'esistenza di sottogruppi nilpotenti auto-normalizzanti in alcuni gruppi semplici
We consider the Suzuki groups and we show that there are no nilpotent self-normalizing subgroups and there are three conjugacy classes of F-projectors, where F is the formation of supersoluble groups.

Sylow 2-subgroups of solvable Q-groups.
A finite group whose irreducible characters are rational valued is called a rational or a Q-group. In this paper we obtain various results concerning the structure of a Sylow 2-subgroup of a solvable Q-group.
