Another presentation of even orthogonal Steinberg groups

Egor Voronetsky

Published 2020-12-22Version 1

We use the pro-group approach to prove that $\mathrm{StO}(2l, R)$ admits van der Kallen's another presentation for any commutative ring $R$ and $l \geq 3$. Moreover, we construct an analog of ESD-transvections in even orthogonal Steinberg pro-groups under some assumptions on their parameters.
