李雅普诺夫分解与莫尔斯分解相等的条件

Conditions for Equality between Lyapunov and Morse Decompositions

Luciana A. Alves, Luiz A. B. San Martin

摘要:

设$Q\rightarrow X$是连续主丛,其群$G$是约化的.在紧致底空间$X$上,赋予遍历概率测度的$Q$的自同构流$ϕ$导致与$Q$相关的标志束的两个分解.一个连续的一个由最好的莫尔斯分解和可测的一个提供的乘法遍历定理。第二个包含在第一个中。在本文中,我们找到充要条件,使他们重合。这两个分解之间的平等意味着连续的扰动下的李雅普诺夫谱保持不变的流量在底空间。

英文摘要:

Let $Q\rightarrow X$ be a continuous principal bundle whose group $G$ is reductive. A flow $ϕ$ of automorphisms of $Q$ endowed with an ergodic probability measure on the compact base space $X$ induces two decompositions of the flag bundles associated to $Q$. A continuous one given by the finest Morse decomposition and a measurable one furnished by the Multiplicative Ergodic Theorem. The second is contained in the first. In this paper we find necessary and sufficient conditions so that they coincide. The equality between the two decompositions implies continuity of the Lyapunov spectra under pertubations leaving unchanged the flow on the base space.
