Pronormal and subnormal subgroups and permutability
James Beidleman, Hermann Heineken (2003)
Bollettino dell'Unione Matematica Italiana
We describe the finite groups satisfying one of the following conditions: all maximal subgroups permute with all subnormal subgroups, (2) all maximal subgroups and all Sylow -subgroups for permute with all subnormal subgroups.
Pronormality, contranormality and generalized nilpotency in infinite groups.
Leonid A. Kurdachenko, Igor Ya. Subbotin (2003)
Publicacions Matemàtiques
This article is dedicated to some criteria of generalized nilpotency involving pronormality and abnormality. Also new results on groups, in which abnormality is a transitive relation, have been obtained.

Representing lattices by homotopy groups of graphs

Commentationes Mathematicae Universitatis Carolinae
In this paper we represent every lattice by subgroups of free groups using the concept of the homotopy group of a graph.

Soluble Groups with Many Černikov Quotients
Silvana Franciosi, Francesco de Giovanni (1985)
Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni
Si studiano i gruppi risolubili non di Černikov a quozienti propri di Černikov. Nel caso periodico tali gruppi sono tutti e soli i prodotti semidiretti con -gruppo abeliano elementare infinito e gruppo irriducibile di automorfismi di che sia infinito e di Černikov. Nel caso non periodico invece si riconduce tale studio a quello dei moduli a quozienti...

Solvable groups with many BFC-subgroups.
O. D. Artemovych (2000)
Publicacions Matemàtiques
We characterize the solvable groups without infinite properly ascending chains of non-BFC subgroups and prove that a non-BFC group with a descending chain whose factors are finite or abelian is a Cernikov group or has an infinite properly descending chain of non-BFC subgroups.
