在研究动力系统的统计特性时,有许多重要的特性,例如,熵,李雅普诺夫指数等。在这篇笔记中,我们想集中在方差σ:C(M)→ R的霍德尔函数。方差出现在双曲映射和流的统计特性中。对于双曲映射T:M →M,Hölder连续函数f:M → R和Gibbs测度(对于Hölder连续函数g),我们可以定义
In the study of the statistical properties of dynamical systems there are a number of important characteristics, e.g., entropy, Lyapunov exponents, etc. In this note we want to concentrate on the variance σ : C(M) → R of Hölder functions. The variance appears in statistical properties for both hyperbolic maps and flows. For a hyperbolic map T : M →M , a Hölder continuous function f : M → R and a Gibbs measure (for a Hölder continuous function g) we can define
