仿正规加权条件型算子
Paranormal weighted conditional type operators
摘要:
本文研究了$L^2(Σ)$上的超正规加权条件期望型算子的几个子类:*-超正规、拟-*-超正规和(n; k)-拟-*-超正规加权条件期望型算子.并给出了这几类谱、点谱、联合点谱、近似点谱和联合近似点谱的一些应用。
英文摘要:
In this paper, some sub-classes of paranormal weighted conditional expectation type operators, such as *-paranormal, quasi-*-paranormal and (n; k)-quasi-*-paranormal weighted conditional expectation type opera- tors on $L^2(Σ)$ are investigated. Also, some applications about the spectrum, point spectrum, joint point spectrum, approximate point spectrum and joint approximate point spectrum of these classes are presented.
