摘要 设T是作用在希尔伯特空间H上的有界线性算子,本文研究T的广义Aluthge变换和广义*-Aluthge变换,并且得到T的广义Aluthge变换的数值域和广义*-Aluthge变换的数值域相等. Let T be a bounded linear operator in a Hilbert space H. We study the properties of the generalized Aluthge transform and the generalized *-Aluthge transform of T. In this paper, we get that both the numerical ranges of the generalized Aluthge transform and the generalized *-Aluthge transform of T are equal.
