在本文中,我们用本质谱刻画了达到正规算子的绝对范数。然后,我们证明了次正规绝对范数达到(或简称AN-算子)的一个结构定理,并推导了算子正规的条件。
In this article, we characterize absolutely norm attaining normal operators in terms of the essential spectrum. Later we prove a structure theorem for hyponormal absolutely norm attaining (or AN-operators in short) and deduce conditions for the normality of the operator.
