On generalised FC-groups in which normality is a transitive relation

We extend to soluble FC∗-groups, the class of generalised FC-groups introduced in [F. de Giovanni, A. Russo, G. Vincenzi, `Groups with restricted conjugacy classes', Serdica Math. J. 28(3) (2002), 241-254], the characterisation of finite soluble T-groups obtained recently in [G. Kaplan, `On T-groups, supersolvable groups and maximal subgroups', Arch. Math. 96 (2011), 19-25]

Gruppi localmente finiti dotati di r-omomorfismi duali completi

Si determinano i gruppi localmente finiti che ammettono un r-omomorfismo duale completo.A characterization is given of the locally finite groups with a complete dual-lattice homomorphism
