利用双重算子积分,从算子平均公理的角度推广了Aluthge变换。它包括由李善衡、李文耀和尹永强定义的平均变换。接下来,我们将给出它的一些性质。特别地,我们将证明可逆矩阵的均值变换的第次迭代收敛到正规矩阵。讨论了由某些算子方法诱导的Aluthge变换的数值值域之间的包含关系。
The Aluthge transformation is generalized in the viewpoint of the axiom of operator means by using double operator integrals. It includes the mean transformation which is defined by S. H. Lee, W. Y. Lee and J. Yoon. Next we shall give some properties of it. Especially, we shall show that then-th iteration of mean transformation of an invertible matrix converges to a normal matrix. Inclusion relations among numerical ranges of induced Aluthge transformations by some operator means are considered.
