Hominin and animal activities in the microstratigraphic record from Denisova Cave (Altai Mountains, Russia)

open access: yes, 2019
Denisova Cave in southern Siberia uniquely contains evidence of occupation by a recently discovered group of archaic hominins, the Denisovans, starting from the middle of the Middle Pleistocene.

Shunkov Groups Saturated with Almost Simple Groups

Algebra and Logic, 2023
A group \(G\) is a Shunkov group if whenever \(H\) is a finite subgroup of \(G\) any two conjugate elements of prime order in the group \(N_G(H)/H\) generate a finite subgroup. The class of such groups forms a generalization of the class of locally finite groups.

Characterizations of the Shunkov groups

open access: yesUkrainian Mathematical Journal, 2008
We study the structure of a family of finite groups of the form L g = 〈a, a g 〉 in a periodic Shunkov group. As a consequence of the obtained result, we get two characterizations of periodic Shunkov groups.

Periodic part in some Shunkov groups

Algebra and Logic, 1999
A group G is saturated with groups in a set X if every finite subgroup of G is embeddable in G into a subgroup L isomorphic to some group in X. We show that a Shunkov group has a periodic part if the saturating set for it coincides with one of the following: {L2(q)}, {Sz(q)}, {Re(q)}, or {U3(2n)}.

The structure of an infinite Sylow subgroup in some periodic Shunkov groups

Discrete Mathematics and Applications, 2002
AbstractWe study periodic groups such that the normaliser of any finite non-trivial subgroup of such a group is almost layer-finite. The class of groups satisfying this condition is rather wide and includes the free Burnside groups of odd period which is greater than 665 and the groups constructed by A. Yu. Olshanskii.We consider the classical question:
