Abstract: (Elsevier)
Using high temperature series expansions of λø 4 4 field theory and their Padé approximants, we have shown that the theory's critical behaviour is characterized by logarithmic corrections to mean field scaling laws. These are related to the triviality of the scaling limit.- field theory: scalar
