Locally isotropic elementary groups

Group Theory 2026-05-08 v2

Abstract

We construct elementary subgroups of all reductive groups of the local isotropic rank 2\geq 2 over rings and prove their basic properties. In particular, our results may be applied to the automorphism groups of any finitely generated projective modules over commutative unital rings of rank 3\geq 3 at every prime ideal.
