$Φ^4$ theory is trivial
Year: 2015
Type: preprint
Abstract: We prove that the $Φ^4$ theory is trivial for any values of the bare coupling constant $λ$ thus extending previous results referring to very strong couplings to the full range of values for this parameter. The method is based on all order properties of the partition and two point functions in the path integral formalism.
