Intersection graphs of almost subnormal subgroups in general skew linear groups

Bui Xuan Hai, Binh-Minh Bui-Xuan, Le Van Chua +1

Let $D$ be a division ring, $n$ a positive integer, and GL $_{n} (D)$ the general linear group of degree $n$ over $D$ . In this paper, we study the induced subgraph of the intersection…

Permutable subgroups in $\GL_n(D)$ and applications to locally finite group algebras

Le Qui Danh, Mai Hoang Bien, Bui Xuan Hai

In this paper we study the existence of free non-abelian subgroups in non-central permutable subgroups of general skew linear groups and locally finite group algebras.

Locally solvable maximal subgroups in division rings

Huynh Viet Khanh, Bui Xuan Hai

Let $D$ be a division ring with center $F$ , and $G$ an almost subnormal subgroup of $D^{*}$ . In this paper, we show that if $G$ contains a non-abelian locally solvable maximal subgro…

Locally solvable subnormal and quasinormal subgroups of division rings

Le Qui Danh, Huynh Viet Khanh

Let $D$ be a division ring with center $F$ , and $G$ a subnormal or quasinormal subgroup of $D^{*}$ . We show that if $G$ is locally solvable, then $G$ is contained in $F$ .

On locally solvable subgroups in division rings

Huynh Viet Khanh

Let $D$ be a division ring with center $F$ , and $G$ a subnormal subgroup of $D^{*}$ . We show that if $G$ is a locally solvable group such that $G^{(i)}$ is algebraic over $F$ , then $…

On free subgroups in maximal subgroups of skew linear groups

Bui Xuan Hai, Huynh Viet Khanh

The study of the existence of free groups in skew linear groups have been begun since the last decades of the 20-th century. The starting point is the theorem of Tits (1972), now o…

A note On subgroups in a division ring that are left algebraic over a division subring

Bui Xuan Hai, Vu Mai Trang, Mai Hoang Bien

Let $D$ be a division ring with center $F$ and $K$ a division subring of $D$ . In this paper, we show that a non-central normal subgroup $N$ of the multiplicative group $D^{*}$ is lef…

On weakly locally finite division rings

Trinh Thanh Deo, Mai Hoang Bien, Bui Xuan Hai

Weakly locally finite division rings were considered in \cite{dbh}, where it was mentioned that the class of weakly locally finite division rings properly contains the class of loc…

On multiplicative subgroups in division rings

Bui Xuan Hai, Nguyen Anh Tu

Let $D$ be a division ring. In this paper, we investigate properties of subgroups of an arbitrary subnormal subgroup of the multiplicative group $D^{*}$ of $D$ . The new obtained resu…

On subgroups in division rings of type $2$

Bui Xuan Hai, Trinh Thanh Deo, Mai Hoang Bien

Let $D$ be a division ring with center $F$ . We say that $D$ is a {\em division ring of type $2$ } if for every two elements $x, y \in D,$ the division subring $F (x, y)$ is a finite d…

On the proof of some theorem on locally nilpotent subgroups in division rings

Bui Xuan Hai, Nguyen Van Thin

In Hai-Thin (2009), there is a theorem, stating that every locally nilpotent subnormal subgroup in a division ring $D$ is central (see Hai-Thin (2009, Th. 2.2)). Unfortunately, the…
