| Samenvatting | In this paper we study truncated finite dimensional models of the
infinite-dimensional equation describing the evolution of even, space-periodic solutions
ofthe Ginzburg-Landau equation. We derive estimates on the position of the global
attractor of the flow, which yield that the magnitude of the Mth mode of the global
attractor decays faster than any algebraic power of M-'. The estimates are independent
of the dimension of the model. In a numerical section we simulate the Row for three
radical low-dimensional models (of two, three and four complex modes); we analyse the
inhence oi ihe number oi modes on the giabai dynamics. Tie iour-dimensionai modei
exhibits the same intricate flow-characteristics as the 32-dimensional model studied by
Keefe. |
