    "abstract": "The formalism of classical and quantum mechanics on phase space leads to\nsymplectic and Heisenberg group representations, respectively. The Wigner\nfunctions give a representation of the quantum system using classical\nvariables. The correspondence between the classical and the quantum criterion\nof separability for the system is obtained in terms of these functions.\n  Entanglement is generic and separability is special. Some applications are\ndiscussed in commonly occuring examples and possibly in exotic systems.",
