Abstract
A new approach to studying the scaling behavior of scalar theory near the G aussian fixed point in d dimensions is presented. For a class of initial da ta an explicit use of the Green's function of the evolution equation is mad e. It is thus discussed under which conditions nonpolynomial relevant inter actions can be generated by the renormalization group flow.
