Itô’s theorem and metabelian Leibniz algebras

Abstract: We prove that the celebrated Itô's theorem for groups remains valid at the level of Leibniz algebras: if g is a Leibniz algebra such that g = A + B, for two abelian subalgebras A and B, then g is metabelian, i.e. [ [g, g], [g, g] ] = 0. A structure type theorem for metabelian Leibniz/Lie algebras is proved. All metabelian Leibniz algebras having the derived algebra of dimension 1 are described, classified and their automorphisms groups are explicitly determined as subgroups of a semidirect product of groups P … Show more

“…gives α 1 , β 2 ≠ 0. If α 2 = 0 and β 1 = 0, then setting x = 1 β2 a − 1 α1β2 a 2 , y = b, z = a 2 we have A = span{x, y, z} with the nonzero products given in (2) where α = α1 β2 . If α 2 = 0 and β 1 ≠ 0 and α 1 = β 2 then choosing x = 1 2α1 a − 1 2α 2 1 a 2 , y = α1+β1 2α1 a 2 + 1 2 b, z = a 2 + b gives A = span{x, y, z} with the nonzero products given in (3).…”

“…Fite [8] and since then they became a very important topic of study within group theory [14]. At the level of Lie, or more general Leibniz algebras, the corresponding concept of metabelian Lie/Leibniz algebra, as 2-step solvable algebra, is also well known [2,6,7]. In this paper we introduce the associative algebra counterpart of a metabelian group by defining a metabelian algebra over a field k as an extension of an abelian algebra by an abelian algebra -the word 'abelian' is borrowed from Lie algebras, i.e.…”
