Abstract

A review of the renormalization group approach to the proof of non perturbative ultraviolet stability in scalar field theories in dimension d=2,3.

Discussions

• One common way to analyze a quantum field theory is to regularize it by introducing an ultraviolet cutoff. After perhaps renormalizing the theory, one would hope that you can remove the cutoff by taki [stackexchange, 7 points]
