摘要
将定义两个从A类算子到亚正规算子的变换T^^的n次迭代T^^n及算子变换T^^(*)的n次迭代群T^^n^(*),并给出它们具有的一些性质.
In this paper, we will define two transformations from class A to the class of hyponormal operators, which are n-th operators transformation T^^n of T^^ and the n-th operators transformation T^^n^(*) of T^^^(*), and give their some properties.
