TLDR
In this paper, fundamental phenomena from three coupled relaxation oscillators are analyzed and a rough bifurcation diagram is given, indicating that 3-torus is popular for weak coupling and chaos is more popular for relatively strong coupling.
Abstract
This paper analyzes fundamental phenomena from three coupled relaxation oscillators. The system nonlinearity is a piecewise linear hysteresis comparator and we can explicitly calculate the return map and its Lyapunov exponents. Then we clarify generation of chaos, 2-torus, 3-torus and various kinds of synchronizations. Also, a rough bifurcation diagram is given. It indicates that 3-torus is popular for weak coupling and chaos is popular for relatively strong coupling. Some of the phenomena are confirmed by laboratory measurements. >

The dimension of chaotic attractors

TL;DR: In this paper, the authors discuss a variety of different definitions of dimension, compute their values for a typical example, and review previous work on the dimension of chaotic attractors, and conclude that dimension of the natural measure is more important than the fractal dimension.

Three coupled oscillators: mode-locking, global bifurcations and toroidal chaos

TL;DR: In this article, the authors describe and explain the aspects of the bifurcation diagram for two-parameter families of torus maps that involve change of mode-locking type, which correspond to the presence of one or two rational relations between the frequencies, respectively.

Three-frequency quasiperiodicity, phase locking, and the onset of chaos

TL;DR: In this article, the authors performed a series of experiments with coupled relaxation oscillators to study three-frequency quasiperiodicity and found strong evidence for the Ruelle-Takens scenario for the transition to chaos although only a small portion of parameter space is occupied by chaos.
