Abstract
We investigate the Polchinski ERG equation for d-dimensional O(N) scalar fi eld theory. In the context of the non-perturbative derivative expansion we find families of regular solutions and establish their relation with the ph ysical fixed points of the theory. Special emphasis is given to the limit N = infinity for which many properties can be studied analytically.
