Conference publicationsAbstractsXVIII conferenceA condition sufficient for nilpotency in groupsMoscow State Institute for Electronics and Mathematics, Russia, 109028, Moscow, B. Tryohsvyatitel'skiy pereulok, 3/12, telephone: (499) 246-28-51, E-mail: kirill.andreyev@yandex.ru 2 pp. (accepted)In my old paper [1] two theorems were proved. Theorem 1. Let G be a tortion-free group, in which every three elements generate a nilpotent subgroup of a bounded class. Then the group G is locally nilpotent. Theorem 2. Let G be a group possessing non-trivial elements of finite order. If every three elements in G generate a nilpotent subgroup of a small class (i. e. less than the order of every non-trivial periodic element of the group), then the group G is locally nilpotent. In the present work I strengthen the theorem 1. Theorem 3. Let G be a tortion-free group, in which every three elements generate a nilpotent subgroup of a bounded class. Then the group G is nilpotent.
