A Nambu-Poisson structure on a manifold can be defined by a $$k$$-vector field satisfying an integrability condition. If $$k=2$$ the Nambu-Poisson structures coincide with Poisson structures. The author first gives a characterization of Nambu-Poisson structures in terms of forms rather than $$k$$-vector fields provided the manifold is endowed with a volume form. Next a description of left invariant Nambu-Poisson tensors on a Lie group in terms of subalgebras of the corresponding Lie algebra is presented. It is also studied under what conditions Nambu-Poisson tensors could be projected onto the corresponding homogeneous space.
