Automorphisms of Free Metabelian Lie Algebras, II

We show that every automorphism of the free metabelian Lie algebra $M_n$ of rank $n\geq 4$ over an arbitrary field $K$ is almost tame; that is, it can be expressed as a product of Chein automorphisms (also called one-row transformations). Moreover, we prove that, for $n\geq 4$, the group $\mathrm{Au
