Considering the Cauchy problem for the critical complex Ginzburg-Landau equation in H1(Rn), weshall show the asymptotic behavior for its solutions in C(0, ∞; H1 (Rn)) ∩ L2(0, ∞; H1,2n/(n-2)(Rn )), n≥ 3.Analogous results also hold in the case that the nonlinearity has the subcritical power in H1(Rn), n≥ 1.
