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…

Generalized power central group identities in almost subnormal subgroups of $\GL_n(D)$

Bui Xuan Hai, Huynh Viet Khanh, Mai Hoang Bien

In this paper, we study almost subnormal subgroups of the general linear group $\GL_n(D)$ of degree $n \geq 1$ over a division ring $D$ that satisfy a generalized power central group…

On division subrings normalized by almost subnormal subgroups in division rings

Trinh Thanh Deo, Mai Hoang Bien, Bui Xuan Hai

Let $D$ be a division ring with infinite center, $K$ a proper division subring of $D$ and $N$ an almost subnormal subgroup of the multiplicative group $D^{*}$ of $D$ . The aim of this…
