This article is dedicated to soluble groups, in which pronormality is a transitive relation. Complete description of such groups is obtained.

Let G be a non-periodic locally solvable group. A characterization is given of the subgroups-D of G for which the map , for all , defines a lattice-endomorphism.

The following results are proved: The center of any finite index subgroup of an irreducible, infinite, nonaffine Coxeter group is trivial; Any finite index subgroup of an irreducible, infinite, nonaffine Coxeter group cannot be expressed as a product of two nontrivial subgroups. These two theorems imply a unique decomposition theorem for a class of Coxeter groups. We also prove that the orbit of each element other than the identity under the conjugation action in an irreducible, infinite,...

In this article we prove an effective version of the classical Brauer’s Theorem for integer class functions on finite groups.

Un sottogruppo di un gruppo si dice nearly normal se ha indice finito nella sua chiusura normale . In questa nota si caratterizzano i gruppi in cui ogni sottogruppo che non sia nearly normal soddisfa una fissata condizione finitaria per diverse scelte naturali della proprietà .
