Stefano Luzzatto, Hiroki Takahasi

AI总结:

基于可计算初始条件,提出并证明了Jakobson-Benedicks-Carleson型定理,给出非一致双曲性(随机动力学)发生的显式可计算下界,并应用于二次族,证明绝对连续不变概率测度对应的参数集测度至少为10^{-5000}。

摘要:

我们基于“可计算的初始条件”提出并证明了一个关于一维映射族中非一致双曲性(随机动力学)发生的Jakobson-Benedicks-Carleson型定理,并为所选参数集的测度提供了“显式、可计算的”下界。作为我们结果的第一个应用,我们证明了二次族f_{a}(x) = x^{2}-a中具有绝对连续不变概率测度的映射对应的参数集至少为10^{-5000}。

英文摘要:

We formulate and prove a Jakobson-Benedicks-Carleson type theorem on the occurence of nonuniform hyperbolicity (stochastic dynamics) in families of one-dimensional maps, based on "computable starting conditions" and providing "explicit, computable," lower bounds for the measure of the set of selected parameters. As a first application of our results we show that the set of parameters corresponding to maps in the quadratic family f_{a}(x) = x^{2}-a which have an absolutely continuous invariant probability measure is at least 10^-5000 !
