| Bosonic Monocluster Expansion (2007) | |||||||||||||||||
Abstract | |||||||||||||||||
| We compute connected Green's functions of a Bosonic field theory with cutoffs by means of a "minimal " expansion which in a single move, interpolating a generalized propagator, performs the usual tasks of the cluster and Mayer expansion. In this way it allows a direct construction of the infinite volume or thermodynamic limit and it brings constructive Bosonic expansions closer to constructive Fermionic expansions and to perturbation theory. | |||||||||||||||||
