The Nowicki conjecture for relatively free algebras

Abstract: A linear locally nilpotent derivation of the polynomial algebra K[Xm] in m variables, over a field K of characteristic 0, is called a Weitzenböck derivation. It is well known from the classical theorem of Weitzenböck that the algebra of constants K[Xm] δ of a Weitzenböck derivation δ is finitely generated. Let m = 2d, and the Weitzenböck derivation δ act on the the polynomial algebra K[X 2d ] in 2d variables as follows:The conjecture was proved by several authors based on different techniques. We apply the sam… Show more

“…Here δ acts on U d and V d in the same way as on X d . In [4] the authors give an explicit set of generators of the algebra of constants of the variety generated by the infinite dimensional Grassmann algebra and of the free metabelian associative algebra. A good part of those result is presented explicitly in the text (Sections 5 and 6).…”

“…They gave a finite generating set for the algebra (𝐹 2𝑛 ′ ) 𝛿 included in the commutator ideal 𝐹 2𝑛 ′ of 𝐹 2𝑛 as a 𝐾[𝑋 𝑛 , 𝑌 𝑛 ] 𝛿 -module. As a continuation of this work a finite generation set for the algebra of constants in the commutator ideal of the free metabelian associative algebra generated by 𝑋 𝑛 ∪ 𝑌 𝑛 as a 𝐾[𝑋 𝑛 , 𝑌 𝑛 ] 𝛿 -bimodule was given in [11]. In the same work, a set of finite generators was obtained for the free algebra in the variety of infinite dimensional Grassmann algebras.…”

“…One may count the Nowicki conjecture for the free metabelian Lie algebra 𝐹 2𝑑 of rank 2𝑑 [10], in which a finite generating set for the algebra (𝐹 2𝑑 ′ ) 𝛿 as a 𝐾[𝑋 𝑑 , 𝑌 𝑑 ] 𝛿 -module was given. Additinally, the Nowicki conjecture was studied for the free metabelian associative algebra of rank 2𝑑 [11]. Also, generators were obtained for algebras of invariants in Grassmann algebras [11].…”
