摘要：
Renormalization group flow equations for scalar λΦ4 are generated using smooth smearing functions. Numerical results for the critical exponent ν in d = 3 are calculated by polynomial truncation of the blocked potential. It is shown that the convergence of ν with the order of truncation can be improved by fine tuning of the smoothness parameter. © 2001 Taylor & Francis Group, LLC.
