Products of commutators of unipotent matrices of index $2$ in $\mathrm{GL}_n(\mathbb H)$

Abstract

The aim of this paper is to show that if $\mathbb{H}$ is the real quaternion division ring and $n$ is an integer greater than $1,$ then every matrix in the special linear group $\mathrm{SL}_n(\mathbb{H})$ can be expressed as a product of at most three commutators of unipotent matrices of index $2$.
