    "abstract": "We formulate the dynamics of the generic quantum system S_{c} comprising a\nmicrosystem S and a macroscopic measuring instrument I, whose pointer positions\nare represented by orthogonal subspaces of the Hilbert space of its pure\nstates. These subspaces are simultaneous eigenspaces of a set of coarse grained\nintercommuting macroscopic observables and, most crucially, their\ndimensionalities are astronomically large, increasing exponentially with the\nnumber, N, of particles comprising I. We formulate conditions under which the\nconservative dynamics of S_{c} yields both a reduction of the wave packet\ndescribing the state of S and a one-to-one correspondence, following a\nmeasurement, between the pointer position of I and the resultant eigenstate of\nS; and we show that these conditions are fulfilled, up to utterly negligible\ncorrections that decrease exponentially with N, by the finite version of the\nColeman-Hepp model.",
