Automorphisms of free metabelian Lie algebras, I

Ualbai Umirbaev

We show that all Chein automorphisms (or one-row transformations) of lower degree $\geq 4$ of a free metabelian Lie algebra $M_{n}$ of rank $n \geq 4$ over an arbitrary field $K$ of c…

Erroneous proofs of the wildness of some automorphisms of free metabelian Lie algebras

Ualbai Umirbaev

The well-known Bachmuth-Mochizuki-Roman'kov Theorem \cite{BM,Romankov85} states that every automorphism of the free metabelian group of rank $\geq 4$ is tame. In 1992 Yu. Bahturin…
