    "abstract": "We review two general criteria for deciding whether a pure bipartite quantum\nstate describing a system of two identical particles is entangled or not. The\nfirst one considers the possibility of attributing a complete set of objective\nproperties to each particle belonging to the composed system, while the second\nis based both on the consideration of the Slater-Schmidt number of the\nfermionic and bosonic analog of the Schmidt decomposition and on the evaluation\nof the von Neumann entropy of the one-particle reduced statistical operators.",
