Ideals of free metabelian Lie algebras and primitive elements.
Innere Lie-Tripelsysteme und J-Ternäre Algebren.
Invariant cones in solvable Lie algebras.
Invariants of Lie color algebras acting on graded algebras
We prove a series of "going-up" theorems contrasting the structure of semiprime algebras and their subalgebras of invariants under the actions of Lie color algebras.
Isomorphisms and derivations in Lie -algebras.
