Determining nodes, finite differences schemes and inertial manifolds. (English) Zbl 0714.34078

Summary: The aim of this paper is to present a connection between the concepts of determining nodes and inertial manifolds with that of finite difference and finite volumes approximation to dissipative partial differential equations. In order to illustrate this connection we consider the one dimensional Kuramoto-Sivashinsky equation as an instructive paradigm. We remark that the results presented here apply to many other equations such as the one dimensional complex Ginzburg-Landau equation, the Chafee- Infante equation, etc.
