Lyapunov exponents for random perturbations of coupled standard maps

Alex Blumenthal, Jinxin Xue, Yun Yang

摘要:

本文给出了一类自然类$2N$维保体积系统在相空间的一个大的非不变子集上表现出强双曲性的随机扰动的第一$N$李雅普诺夫指数之和的定量估计.我们的设置所涵盖的具体模型包括系统的耦合标准地图,在“弱”和“强”耦合制度。

英文摘要:

In this paper, we give a quantitative estimate for the sum of the first $N$ Lyapunov exponents for random perturbations of a natural class $2N$-dimensional volume-preserving systems exhibiting strong hyperbolicity on a large but noninvariant subset of phase space. Concrete models covered by our setting include systems of coupled standard maps, in both `weak' and `strong' coupling regimes.
