摘要：

The study of the Wegner-Houghton equation in the local-potential approximation yields infrared-stable renormalization-group trajectories that are rejected by field theory. The most stable one corresponds to an approach to the infrared-stable fixed point from the unusual side, yielding negative correction-to-scaling amplitudes as already observed in a binary mixture. We also show how this affects the analysis made by Baker and Kincaid, who concluded that the field-theoretic framework fails in describing the critical behavior of the spin-(1/2 Ising model at d=3. © 1990 The American Physical Society.
