Nilpotency of locally isotropic $K_{1}$ -functor

Egor Voronetsky

We show that the $K_{1}$ -functor modeled on locally isotropic reductive groups is hypoabelian if the base ring has finite Bass--Serre dimension and, for the Tits index $ \…

Weyl elements in isotropic reductive groups

Egor Voronetsky

We study Weyl elements in isotropic reductive groups over commutative rings. Our main result in an explicit formula for squares of such elements. We also classify these elements in…

Locally isotropic Steinberg groups I. Centrality of the $K_{2}$ -functor

Egor Voronetsky

We begin to study Steinberg groups associated with a locally isotropic reductive group $G$ over a arbitrary ring. We propose a construction of such a Steinberg group functor as a g…
