Non-perturbative scaling in the scalar theory
arXiv:hep-th/0001060 · doi:10.1103/PhysRevD.62.027701
Abstract
A new approach to study the scaling behavior of the scalar theory near the Gaussian fixed point in $d$-dimensions is presented. For a class of initial data an explicit use of the Green's function of the evolution equation is made. It is thus discussed under which conditions non-polynomial relevant interactions can be generated by the renormalization group flow.
