Noetherianness of wreath products of Abelian Lie algebras with respect to equations of universal enveloping algebra

摘要

It is proved that a wreath product of two Abelian finite-dimensional Lie algebras over a field of characteristic zero is Noetherian w.r.t. equations of a universal enveloping algebra. This implies that an index 2 soluble free Lie algebra of finite rank, too, has this property.
