具有长程相互作用的双曲动力系统的同步时间

Synchronization time in a hyperbolic dynamical system with long-range interactions

Rodrigo Frehse Pereira, Sandro Ely de Souza Pinto, Sergio Roberto Lopes

摘要:

我们证明了在耦合非光滑混沌映射格中完全同步的阈值是由沿同步子空间横向方向的线性稳定性决定的。我们仔细研究的同步时间,并表明,不充分的观察系统的演变导致错误的结果。我们提出了仔细的数值实验和严格的数学解释证实了这一事实,允许推广涉及双曲耦合映射格子。

英文摘要:

We show that the threshold of complete synchronization in a lattice of coupled non-smooth chaotic maps is determined by linear stability along the directions transversal to the synchronization subspace. We examine carefully the sychronization time and show that a inadequate observation of the system evolution leads to wrong results. We present both careful numerical experiments and a rigorous mathematical explanation confirming this fact, allowing for a generalization involving hyperbolic coupled map lattices.
