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.
