Torsion-free rings with finite automorphism groups

Research output: Contribution to journalArticlepeer-review

Abstract

The paper considers finite rank torsion-free rings, i.e, subrings of finite-dimensional rational algebras. The main result of the paper is the characterization of finite rank torsion-free rings with finite automorphism groups. Nontrivial examples of rings R with AutR finite have been constructed.
