Abstract
An effect of multiplicative noise in the time-dependent Ginzburg-Landa u model is reported, namely, that noise at a relatively low intensity induces a phase transition towards an ordered state, whereas strong no ise plays a destructive role, driving the system back to its disordere d state through a reentrant phase transition. The phase diagram is cal culated analytically using a mean-field,theory and a more sophisticate d approach and is compared with the results from extensive numerical s imulations.
