For infinitesimal changes of vertex functions under infinitesimal variation of all renormalized parameters, linear combinations are found such that the net infinitesimal changes of all vertex functions are negligible relative to those functions themselves at large momenta in all orders of renormalized perturbation theory. The resulting linear first order partial differential equations for the asymptotic forms of the vertex functions are, in quantum electrodynamics, solved in terms of one… Expand
Renormalization constants and asymptotic behaviour in quantum electrodynamics
Abstract Using dimensional regularization, a field theory contains at least one parameter less than usual with the dimension of mass. The Callan-Symanzik equations for the renormalization constantsExpand
Small-distance-behaviour analysis and Wilson expansions
A previously described method to obtain the asymptotic forms of vertex functions at large momenta is, with the help of Wilson operator product expansion formulas, extended to momenta where the vertexExpand
The theory of non-renormalizable interactions: The large N expansion
A particular class of non-renormalizable interactions is studied in the infinite cut-off limit. In this paper we consider the quadrilinear interaction of an N-component field; the Lagrangian isExpand
Explicit construction of the renormalization group transformations in ϕ4 field theory
Abstract The counterterms of a ϕ 4 quantum field theory are decomposed into contributions corresponding to forests of divergent generalized vertices. A partial summation of the perturbation seriesExpand

It is pointed out how one can find iterations of functions which do not satisfy the perturbative boundary condition and the algorithm has been implemented in REDUCE and several examples are discussed. Expand
Φ3 theory in six dimensions and the renormalization group
Abstract Φ 3 field theory in six space-time dimensions is used as a testing ground for the renormalization group. The consistency of the new method devised by 't Hooft is verified at the two-loopExpand
Non-analytic mass behaviour and the renormalization group
In 't Hooft-Weinberg renormalized spinor quantum electrodynamics, the leading mass singularity for m → 0 is found to be m3(−ln m)10 for gauge-invariant vertex functions at non-exceptional momentumExpand
Applications of quantum field theory to statistical mechanics
Abstract Several concepts of quantum field theory in which Symanzik's work has been essential, have played a central role in statistical mechanics as well. The existence of a scaling limit near aExpand
Renormalization theory and ultraviolet stability for scalar fields via renormalization group methods
A self-contained analysis is given of the simplest quantum fields from the renormalization group point of view: multiscale decomposition, general renormalization theory, resummations of renormalizedExpand
Divergences in Perturbation Theory
Loop corrections to the tree level results turn out to be divergent, or very large in certain cases. The physical reason for these divergences is that the system interacts with an infinite (or veryExpand


Renormalizable models with simple symmetry breaking
If to a Lagrangian density with invariance under a continuous group of linear transformations of the fields a term linear or bilinear in the fields is added, the symmetry is in general reduced andExpand
