Abstract
We prove that to all orders in perturbation expansion, the critical exponents of a phase transition in a -dimensional () system with short-range exchange and a random quenched field are the same as those of a ()-dimensional pure system. Heuristic arguments are given to discuss both this result and the random-field Ising model for .
