SOLVABLE 3-LIE ALGEBRAS WITH A MAXIMAL HYPO-NILPOTENT IDEAL N

RUI-PU BAI, CAI-HONG SHEN, AND YAO-ZHONG ZHANG

Abstract. This paper obtains all solvable 3-Lie algebras with them-dimensional filiform 3-Lie algebraN (m≥5) as a maximal hypo-nilpotent ideal, and proves that them-dimensional filiform 3-Lie algebra N can’t be as the nilradical of solvable non-nilpotent 3-Lie algebras. By means of one dimensional extension of Lie algebras to the 3-Lie algebras, we get some classes of solvable Lie algebras directly.

Key words. 3-Lie algebra, hypo-nilpotent ideal, filiform n-Lie algebra.
