From Anosov’s Dynamics on a Surface of Negative Curvature to Electronic Generator of Robust Chaos

Authors: Kuznetsov S. P.

Background and Objectives: Systems with hyperbolic chaos should be of preferable interest due to structural stability (roughness) that implies insensitivity to variation of parameters, manufacturing imperfections, interferences, etc. However, until recently, exclusively formal mathematical examples of this kind of dynamical behavior were known.

Chaos in the System of Three Coupled Rotators: from Anosov Dynamics to Hyperbolic Attractor

Authors: Kuznetsov S. P.

The work presents an example of a system with chaotic dynamics built of three rotators by modifying a conservative system with hyperbolic Anosov dynamics. Results of a computational study of chaotic dynamics are considered (portraits of attractors, time dependences of the variables, Lyapunov exponents, and spectra) and good correspondence is observed between the dynamics on the attractor of the proposed system with the reduced model, characterized by the Anosov dynamics at appropriately defined energy.
