论文摘要

对于双曲线流$φ_T$,我们检查了gibb的点$ W $的GIBB $ w $的$ \ int_0^t g(φ_tw)dt-a t \ in( - e^{ - εn},e^{ - εn},e^{ - εn})$ n \ at $ n \ to $ n \ to \ n \ to \ infty $ infty $ and uftty $ and $ t-iS uffty and $ t \ geq n $,这类似于局部中央限制定理。间隔$(-e^{ - εn},e^{ - εn})$的事实是,作为$ n \ to \ infty $的成倍收缩,导致了几个困难。在某些几何假设下,我们建立了一个急剧的较大偏差结果,并以$ c(a)ε_ne^{γ(a)t} $和速率函数$γ(a)\ leq 0。 \ to \ infty $和$ t \ geq n。$

For hyperbolic flows $φ_t$ we examine the Gibbs measure of points $w$ for which $$\int_0^T G(φ_t w) dt - a T \in (- e^{-εn}, e^{- εn})$$ as $n \to \infty$ and $T \geq n$, provided $ε> 0$ is sufficiently small. This is similar to local central limit theorems. The fact that the interval $(- e^{-εn}, e^{- εn})$ is exponentially shrinking as $n \to \infty$ leads to several difficulties. Under some geometric assumptions we establish a sharp large deviation result with leading term $C(a) ε_n e^{γ(a) T}$ and rate function $γ(a) \leq 0.$ The proof is based on the spectral estimates for the iterations of the Ruelle operators with two complex parameters and on a new Tauberian theorem for sequence of functions $g_n(t)$ having an asymptotic as $ n \to \infty$ and $t \geq n.$
