Bounded generation of Steinberg groups over Dedekind rings of arithmetic type

Boris Kunyavskii, Andrei Lavrenov, Eugene Plotkin +1

The main result of the present paper is bounded elementary generation of the Steinberg groups $St (Φ, R)$ for simply laced root systems $Φ$ of rank $\geq 2$ and arbitrary Ded…

Another presentation for symplectic Steinberg groups

Andrei Lavrenov

We solve a classical problem of centrality of symplectic $K_{2}$ , namely we show that for an arbitrary commutative ring $R$ , $l \geq 3$ the symplectic Steinberg group $\mathrm{…
