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 -operators in short) and deduce conditions for the normality of the operator.

超正态绝对范数获得算子的表示
在本文中,我们根据基本谱描述了绝对范数获得正规算子的特征。稍后我们证明了次正规绝对范数达到的结构定理(或- 运算符)并推导出运算符的正态性条件。
