$\mathrm{PSL}_2(\mathbb{R})$的$L^1$点态遍历定理的失效

Failure of the $L^1$ pointwise ergodic theorem for $\mathrm{PSL}_2(\mathbb{R})$

Lewis Bowen, Peter Burton

摘要:

Amos Nevo在概率空间上关于球平均和每个$p>1$的$\mathrm{PSL}_2(\mathbb{R})$的保测度作用的$L^p$中建立了点态遍历定理。本文通过显式例子说明Nevo定理不能推广到$p=1$。

英文摘要:

Amos Nevo established the pointwise ergodic theorem in $L^p$ for measure-preserving actions of $\mathrm{PSL}_2(\mathbb{R})$ on probability spaces with respect to ball averages and every $p>1$. This paper shows by explicit example that Nevo's Theorem cannot be extended to $p=1$.
