Transformation Groups Aims and scope Submit manuscript

Abstract

Extending results of Rais–Tauvel, Macedo–Savage, and Arakawa–Premet, we prove that under mild restrictions on the Lie algebra \( \mathfrak{q} \) having the polynomial ring of symmetric invariants, the m-th Takiff algebra of \( \mathfrak{q} \), \( \mathfrak{q} \)m⟩, also has a polynomial ring of symmetric invariants.
