Algebraic obstructions to sequential convergence in Hausdorrf abelian groups
International Journal of Mathematics and Mathematical Sciences, 1998 Given an abelian group G and a non-trivial sequence in G, when will it be possible to construct a Hausdroff topology on G that allows the sequence to converge?

On characterized subgroups of compact abelian groups
Topology and its Applications, 2013 A subgroup \(H\) of a topological abelian group \(X\) is called characterized if there exists a sequence \(\mathfrak{u}=\{u_n\}\) of characters of \(X\) such that \(H=s_{\mathfrak{u}}(X)\), where \(s_{\mathfrak{u}}(X):=\{x\in X| (u_n,x)\to 0 \text{ in } \mathbb{T}\}\) and \(\mathbb T\) is the group of reals modulo \(\mathbb Z\).

On the nonperiodic groups, whose subgroups of infinite special rank are transitively normal
Доповiдi Нацiональної академiї наук УкраїниThis paper devoted to the nonperiodic locally generalized radical groups, whose subgroups of infinite special rank are transitively normal. We proved that if such a group G includes an ascendant locally nilpotent subgroup of infinite special rank, then G

Metahamiltonian groups and related topics [PDF]
International Journal of Group Theory, 2013 A group is called metahamiltonian if all its non-abelian subgroups are normal. This aim of this paper is to provide an updated survey of researches concerning certain classes of generalized metahamiltonian groups, in various contexts, and to prove some ...

Crepant resolutions and A-Hilbert schemes in dimension four [PDF]
The aim of this thesis is to improve our understanding of when crepant resolutions exist in dimension four. In three dimensions [BKR01] proved that for any finite subgroup G ⊂ SL(3,C) the G-Hilbert scheme G-Hilb(C3) gives a crepant resolution of the ...

Commutative group algebras of highly torsion-complete abelian $p$-groups [PDF]
, 2003 summary:A new class of abelian $p$-groups with all high subgroups isomorphic is defined. Commutative modular and semisimple group algebras over such groups are examined. The results obtained continue our recent statements published in Comment. Math. Univ.

Groups whose proper subgroups of infinite rank have polycyclic-by-finite conjugacy classes [PDF]
International Journal of Group Theory, 2016 A group G is said to be a (PF)C-group or to have polycyclic-by-finite conjugacy classes, if G/C_{G}(x^{G}) is a polycyclic-by-finite group for all xin G. This is a generalization of the familiar property of being an FC-group.

Infinite groups with fixed point properties
, 2007 We construct finitely generated groups with strong fixed point properties. Let Xac be the class of Hausdorff spaces of finite covering dimension which are mod–p acyclic for at least one prime p.
