From nonlinear scaling fields to critical amplitudes
Y. Meurice, S. Niermann
We propose to combine the nonlinear scaling fields associated with the high-temperature (HT) fixed point, with those associated with the unstable fixed point, in order to calculate…

Examples of overlapping convergent expansions of scaling variables
Y. Meurice, S. Niermann
We construct series expansions for the scaling variables (which transform multiplicatively under a renormalization group (RG) transformation) in examples where the RG flows, going…

Non-Perturbative Aspects of Scalar Field theory
Y. Meurice, S. Niermann, G. Ordaz
Using the hierarchical approximation, we discuss the cut-off dependence of the renormalized quantities of a scalar field theory. The naturalness problem and questions related to tr…
