WebLyapunov exponent is a measure of the exponential rate of nearby trajectories in the phase-space of a dynamical system. In other words, it quantifies how fast converge or diverge trajectories that start close to each other, quantifying the strength of chaos in the system. The divergence of such trajectories can be defined as GGteOt (1) where O WebThe choice of an indicator is goal oriented. To illustrate, frequency map discerns regions of regular and chaotic motion [6], [7]. Similarly, Lyapunov indicators discriminate between regular and chaotic motions. Additionally, they can successfully compute stable, unstable, and Lagrangian manifolds [10].
