摘要

Extensive numerical computations have been carried out using the Kuramoto-Sivashinsky equation which is one of the simplest PDE's which exhibit chaotic behavior. A period-doubling route to chaos has been located which conforms with the Feigenbaum scenario. The chaotic dynamics just beyond the accumulation point are calculated using highly accurate methods from which a picture of the attractor can be constructed. In particular we provide strong numerical evidence of the self-similarity of the attractor. In order to achieve this, magnifications of the attractor of order 10~6 are needed, showing the high accuracy requirements. As far as we know, this has not been done previously for an infinite-dimensional dynamical system.
