具有无穷测度的非马氏流的更新定理和混合

Renewal theorems and mixing for non Markov flows with infinite measure

Ian Melbourne, Dalia Terhesiu

摘要:

我们得到的结果混合的一大类(不一定马尔可夫)无限测度半流和流。埃里克森证明,除其他事项外,强更新定理在相应的i.i.d.设置.利用算子更新理论,我们将埃里克森的方法扩展到确定性(即非独立同分布)。连续时间设置,并因此获得混合结果。我们的结果适用于间歇半流和流动的Pomeau-Manneville型(马尔可夫和nonMarkov),和半流和流动的Collet-Eckmann映射不可积的屋顶功能。

英文摘要:

We obtain results on mixing for a large class of (not necessarily Markov) infinite measure semiflows and flows. Erickson proved, amongst other things, a strong renewal theorem in the corresponding i.i.d. setting. Using operator renewal theory, we extend Erickson's methods to the deterministic (i.e. non-i.i.d.) continuous time setting and obtain results on mixing as a consequence. Our results apply to intermittent semiflows and flows of Pomeau-Manneville type (both Markov and nonMarkov), and to semiflows and flows over Collet-Eckmann maps with nonintegrable roof function.
