On Levi factors of derivation algebras and the radical embedding problem
Problem: given a finite-dimensional nilpotent associative fc-algebra N, find all unital associative A>algebras A such that rad A -N.An approach: which subalgebras of Der* N are images of Lie homomorphisms A/N-^Ώer k NΊ Here the author constructs N over very general fields k such that the "Levi factor" of Όer …
