    "abstract": "In the context of the decoherent histories approach to quantum theory, it is\nshown that a class of macroscopic configurations consisting of histories of\nlocal densities (number, momentum, energy) exhibit negligible interference.\nThis follows from the close connection of the local densities with the\ncorresponding exactly conserved (and so exactly decoherent) quantities, and\nalso from the observation that the eigenstates of local densities (averaged\nover a sufficiently large volume) remain approximate eigenstates under time\nevolution. The result is relevant to the derivation of hydrodynamic equations\nusing the decoherent histories approach.",
