Automorphisms of free metabelian Leibniz algebras.

In this work, we represent free metabelian Leibniz algebras as the wreath product of abelian Leibniz algebras. We obtained an explicit matrix form for the IA-automorphisms of free metabelian Leibniz algebras of finite rank over a field K of characteristic zero. Then we describe a set of generators for the group of all automorphisms of the free metabelian Leibniz algebras of rank n. [ABSTRACT FROM AUTHOR]
