C_0类算子的无界交换子

The unbounded commutant of an operator of class C_0

Hari Bercovici

摘要:

本文用{T}'中的有界算子来描述与C_0类的给定算子T交换的闭的、稠密定义的线性变换.我们的结果扩展了Sarason的亏损指数为1的运营商,和马丁的情况下,任意有限的指数。

英文摘要:

We describe the closed, densely defined linear transformations commuting with a given operator T of class C_0 in terms of bounded operators in {T}'. Our results extend those of Sarason for operators with defect index 1, and Martin in the case of arbitrary finite index.
