Torsion subgroups of Whitehead groups of graded division algebras

Huynh Viet Khanh, Nguyen Duc Anh Khoa, Nguyen Dinh Anh Khoi

The paper investigates the torsion subgroup of the Whitehead group of a graded division algebra, deriving explicit formulas for this subgroup in unramified, totally ramified, and s…

Free subgroups in weighted Leavitt Path Algebras

Huynh Viet Khanh

We study unit groups of weighted Leavitt path algebras. Let be a field of characteristic and let be a finite connected weighted graph. We prove that $L_K(E,ω)^\ti…

Abelian maximal subgroups of valued division algebras

Huynh Viet Khanh

Let be a division ring. We study when the multiplicative group can contain an abelian maximal subgroup. We prove that this cannot occur for any noncommutative tame finite…

On Congruence Theorem for valued division algebras

Huynh Viet Khanh, Nguyen Duc Anh Khoa

Let be a field equipped with a Henselian valuation, and let be a tame central division algebra over the field . Denote by the torsion subgroup of the…
