Technique and results of numerical test for hyperbolic nature of attractors for reduced models of distributed systems
A test of hyperbolic nature of chaotic attractors, based on an analysis of statistics distribution of angles between stable and unstable subspaces, is applied to reduced finite­dimensional models of distributed systems which are the modifications of the Swift- Hohenberg equation and Brusselator model, as well as to the problem of parametric excitation of standing waves by the modulated pump.
