关于非交换L_{p} -空间的多指标加权遍历定理

On multiparameter Weighted ergodic theorem for Noncommutative L_{p}-spaces

Farrukh Mukhamedov, Maksut Mukhamedov, Seyit Temir

摘要:

本文考虑了具有正规、半有限、忠实迹的von Neumann代数$\M$的$T_{1},..., T_{d}$绝对压缩,证明了对每个有界Besicovitch权$\{a(\kb)\}_{\kb\in\bn^d}$和每个$x\in L_{p}(\M)$,($p>1$),平均值A_{\Nb}(x)= \frac{1}{|\Nb|} \limits_{\kb=1}^{\Nb} a(\kb)\Tb^{\kb}(x).在$L_{p}(\M)$中几乎均匀地双侧收敛。

英文摘要:

In the paper we consider $T_{1},..., T_{d}$ absolute contractions of von Neumann algebra $\M$ with normal, semi-finite, faithful trace, and prove that for every bounded Besicovitch weight $\{a(\kb)\}_{\kb\in\bn^d}$ and every $x\in L_{p}(\M)$, ($p>1$) the averages A_{\Nb}(x)=\frac{1}{|\Nb|}\sum\limits_{\kb=1}^{\Nb}a(\kb)\Tb^{\kb}(x). converge bilaterally almost uniformly in $L_{p}(\M)$.
