Arithmetically-free group-gradings of Lie algebras: II
Wolfgang Alexander Moens
We study group-graded Lie algebras L with finite support X. We show that L is nilpotent of |X|-bounded class if X is arithmetically-free. Conversely: we show that Y supports the gr…

Arithmetically-free group-gradings of Lie algebras
Wolfgang Alexander Moens
A Lie algebra L is known to be nilpotent if it admits a grading by (Zp, +) with support X not containing 0. It is also known that the class of L can be bounded by some explicit fun…
