    "abstract": "We present local invariants of multi-partite pure or mixed states, which can\nbe easily calculated and have a straight-forward physical meaning. As an\napplication, we derive a new entanglement criterion for arbitrary mixed states\nof $n$ parties. The new criterion is weaker than the partial transposition\ncriterion but offers advantages for the study of multipartite systems. A\nstraightforward generalization of these invariants allows for the construction\nof a complete set of observable polynomial invariants.",
