Spatially periodic equilibria A(X, T) = √1 − q2 e iqX+iϕ 0 are the locally preferred planform for the Ginzburg‐Landau equation ∂TA = ∂2XA + A − A|A|2. To describe the global spatial behavior, an evolution equation for the local wave number q can be derived formally. The local wave number q satisfies approximately a so called phase diffusion equation ∂τq = ∂2ξh(q). It is the purpose of this paper to explain the extent to which the phase diffusion equation is valid by proving estimates for this formal approximation. (© 2004 WILEY‐VCH Verlag GmbH & Co.
