A scaling analysis of nonlinear critical slowing down on the basis of a Landau-type relaxation equation, shows that the critical exponents, Δ(l) and Δ(nl) of the linear and nonlinear relaxation times of the order parameter are related by Δ(nl)=Δ(l)-β. Generally if Q scales like Δ TβQ one has ΔQ(l)-ΔQ(nl)=βQ but a different relaxation may occur in systems with oscillatory modes.
