Abstract. For the Ginzburg-Landau equation and similar non-linear parabolic equations on the real line, we show the local stability of the slowest monotonic front solution by computing explicitly the leading term in the asymptotic behavior of a small perturbation as $t \to \infty$. The proof is based on the Renormalization Group method for parabolic equations.
