How long do numerical chaotic solutions remain valid
@article{Sauer1997HowLD, title={How long do numerical chaotic solutions remain valid}, author={Tim Sauer and Celso Grebogi and James A. Yorke}, journal={Physical Review Letters}, year={1997}, volume={79}, pages={59-62} }
Dynamical conditions for the loss of validity of numerical chaotic solutions of physical systems are already understood. However, the fundamental questions of {open_quotes}how good{close_quotes} and {open_quotes}for how long{close_quotes} the solutions are valid remained unanswered. This work answers these questions by establishing scaling laws for the shadowing distance and for the shadowing time in terms of physically meaningful quantities that are easily computable in practice. The scaling…

It is argued that the effect of unstable dimension variability is more intense when the invariant chaotic set of the system loses transversal stability through a blowout bifurcation.

It is shown that unstable-dimension variability can occur in wide parameter regimes of chaotic systems with an invariant subspace such as systems of coupled chaotic oscillators, and this paper investigates this phenomenon by investigating a class of deterministic models.

It is shown that the probability distribution of the shadowing time contains two distinct scaling behaviors: an algebraic scaling for short times and an exponential scaling for long times, and the small-time algebraic behavior appears to be universal.
