While the theorem has been shown to hold for a wide range of many-body models, it is frequently ‘violated’ by results derived from the same models using numerical techniques. This raises the question of how scientists regulate their theoretical commitments in such cases, given that the models, too, are often described as approximations to the underlying ‘full’ many-body problem. date: 2005 date_type: published refereed: TRUE citation: Gelfert, Axel (2005) Mathematical Rigor in Physics: Putting Exact Results in Their Place.
