Torsion subgroups of Whitehead groups of graded division algebras

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

In this paper, we study the torsion subgroup, which is denoted by ${\mathrm{TK}}_1(E)$, of the Whitehead group $E^{\ast }/[E^{\ast },E^{\ast }]$ of a graded division algebra $E$ which is finite dimension…
