We describe the Formula: see text-derivations and transposed Poisson structures of the Nambu 3-Lie algebras Formula: see text and Formula: see text. Specifically, we first present that Formula: see text is finitely generated and graded. Then we find that Formula: see text has non-trivial Formula: see text-derivations and admits only trivial transposed Poisson structures. The 3-Lie algebra Formula: see text admits non-trivial transposed Poisson structures.
Jiang et al. (Fri,) studied this question.
