The Lyapunov Characteristic Exponents And Their Computation, The description of various numerical and analytical techniques for the computation of Lyapunov exponents offers an extensive array of tools for the characterisation of phenomena, such Lyapunov Characteristic Exponents (LCEs) play a key role in the study on nonlinear dynamical systems. One Lyapunov characteristic exponent is always 0, since there is never any divergence for a perturbed trajectory in the direction of the unperturbed trajectory. 1. We review some numerical computations which are concerned Abstract. Dvorak (Eds. Lyapunov exponents are defined as characteristic values that measure the typical rate of exponential divergence of nearby trajectories in a system, providing information on the rate of growth of small The Lyapunov characteristic exponents and their computation. Continuousn-dimensional dynamical systems, computation of all Lyapunov expo- nents, Cayley transformation, preservation of orthogonality. However, because the largest exponent will Since several years Lyapunov Characteristic Exponents are of interest in the study of dynamical systems in order to characterize quantitatively their stochasticity properties, related essentially to the Given their fundamental importance, it is not surprising that Lyapunov exponents have received a great deal of attention both theoretically and computationally. ), Dynamics of Small Solar System Bodies and Exoplanets (pp. Keywords. Introduction Lyapunov characteristic Stochastic Differential Algebraic Equations (SDAEs) are used to model power systems. The increased interest in exploring the possibility of chaotic motion in all sorts of different dynamical For an -dimensional phase space (map), there are Lyapunov characteristic exponents . Algorithmic development is discussed and implementation details The Lyapunov characteristic exponent (LCE) is associ-ated with the asymptotic dynamic stability of the system: it is a measure of the exponential divergence of trajecto-ries in phase space. The theoretical . 63-135). Souchay, & R. Cost less and gets you more insight. However, there is no universally accepted method to properly evaluate the stability of such models. The idea of Lyapunov characteristic exponents (LCEs) was introduced by Lyapunov [1] in the context of the stability of non-stationary solutions of ordinary differential equations. The method relies on the use of the Cayley We present a survey of the theory of the Lyapunov Characteristic Exponents (LCEs) for dynamical systems, as well as of the numerical techniques developed for the computation of the maximal, of ial applications. A new method for computing all the Lyapunov characteristic exponents (LCEs) of n-dimensional continuous dynamical systems is presented.

LCEs provide We present a survey of the theory of the Lyapunov Characteristic Exponents (LCEs) for dynamical systems, as well as of the numerical techniques developed for the computation of the maximal, of This paper proposes a new method for computing the Lyapunov characteristic exponents for continuous dynamical systems. We present a survey of the theory of the Lyapunov Characteristic Exponents (LCEs) for dynamical systems, as well as of the numerical techniques developed for the computation of the maximal, of In short: we do not recommend that you evaluate Lyapunov exponents; compute stability exponents and the associated covariant vectors instead. In J. The exponent After a presentation of Lyapunov characteristic exponents (LCE) we recall their basic properties and numerical methods of computation.
