Operator algebras and probability theory supply guiding principles for constructive quantum field theory and rigorous statistical mechanics.
The paper is a set of notes on the van Hove model that covers cutoff removal, existence of ground and KMS states for a point source, and Bose-Einstein condensation in infinite volume, but states it contains no essentially new results.
