Some Convergence Theorems for Operator Sequences

Heybetkulu Mustafayev

摘要:

设$A,$、$T$和$B$是巴拿赫空间上的有界线性算子.本文主要研究序列$\left\{ A^{n}TB^{n}\right\} $和$\left\{ \frac{1}{n}\sum_{i=0}^{n-1}A^{i}TB^{i}% \right\} $依算子范数收敛的充要条件。这些结果适用于Toeplitz,组合和模型运营商。并对有关问题进行了讨论。

英文摘要:

Let $A,$ $T$ and $B$ be bounded linear operators on a Banach space. This paper is concerned mainly with finding some necessary and sufficient conditions for convergence in operator norm of the sequences $\left\{ A^{n}TB^{n}\right\} $ and $\left\{ \frac{1}{n}\sum_{i=0}^{n-1}A^{i}TB^{i}% \right\} $. These results are applied to the Toeplitz, composition and model operators. Some related problems are also discussed.
