我们研究作为 Pomeau-Manneville 型间歇映射的时间相关组合而产生的动力系统。我们为适当缩放和集中的伯克霍夫式部分和建立了中心极限定理,并对收敛速度进行了估计。对于从某个参数范围选择的映射,但无需额外假设映射如何随时间变化,只要部分和的方差增长得足够快,我们就可以获得自规范 CLT。当根据平移不变概率测量随机选择图时,我们确定了淬火 CLT 保持的条件(假设纤维居中)。最后,我们展示了间歇准静态系统的多元 CLT。我们的方法基于斯坦因法线逼近法。
We study dynamical systems arising as time-dependent compositions of Pomeau-Manneville-type intermittent maps. We establish central limit theorems for appropriately scaled and centered Birkhoff-like partial sums, with estimates on the rate of convergence. For maps chosen from a certain parameter range, but without additional assumptions on how the maps vary with time, we obtain a self-norming CLT provided that the variances of the partial sums grow sufficiently fast. When the maps are chosen randomly according to a shift-invariant probability measure, we identify conditions under which the quenched CLT holds, assuming fiberwise centering. Finally, we show a multivariate CLT for intermittent quasi-static systems. Our approach is based on Stein’s method of normal approximation.
