Linearization of finite subgroups of Cremona groups over non-closed fields

Boris Kunyavskii

We study linearizability properties of finite subgroups of the Cremona group in the case where is a global field, with the focus on the local-global princi…

Birational properties of word varieties

Tatiana Bandman, Boris Kunyavskii, Alexei N. Skorobogatov

We prove that the subvariety of given by the matrix equation , where is a word in two letters, is closely related to an explicit smooth conic bund…

Bracket width of current Lie algebras

Boris Kunyavskii, Ievgen Makedonskyi, Andriy Regeta

The length of an element of a Lie algebra is defined as the smallest number needed to represent as a sum of brackets. The bracket width of is defined as sup…

Sha-rigidity of Chevalley groups over local rings

Elena Bunina, Boris Kunyavskii

We prove that every locally inner endomorphism of a Chevalley group (or its elementary subgroup) over a local ring with an irreducible root system of rank >1 (with 1/2 for the syst…
