摘要
通过对一耦合映射系统的伸长数的计算 ,揭示在计算绝对值很小的最大Lyapunov指数λ1时收敛特别慢的原因 .改进了计算λ1的方法 ,提高了λ1的收敛效率 。
Based on the analysis of the “stretching numbers”, the difficulty of convergence in computing extremely small largest positive Lyapunov exponents is elucidated. The transient process with large explosion rate is responsible for this difficulty. The convergence rate can be greatly enhanced by eliminating sufficiently long transient.
