According to a recently given ergodic condition for Hermitian many-body models the thermodynamic limit and irreversibility are necessary but by themselves not sufficient. The sufficient condition turns out to be the existence of a zerofrequency mode. It is measured by an infinite product of the recu

## Abstract This paper discusses the theory and application of the Maximum Entropy Method (MEM) to the reconstruction of Magnetic Resonance (MR) images. It is shown that the MEM is inappropriate for MR image reconstruction and that the usual heuristic justification is invalid in this case. The appl
In recent work on outflow boundary conditions for Navier-Stokes equations by Papanastasiou et al. (Int. j. numer. methods fluids, 14, 587-608 (1992)) a choice has been proposed which can formally be described as imposing no boundary condition at all. This of course leads to an underdetermined proble
