摘要: Abstract We discuss the euclidean φ 4 field theory, and critical behavior in ferromagnetic systems four dimensions. It is rigorously shown that there are at most logarithmic corrections to mean law of magnetic susceptibility X = ΣS 2 (0, x ). Furthermore, if any such present a continuum limit which used construct limiting theory would be non-interacting. Our analysis extends variables belong Griffiths-Simon class.
