有界线性算子的性质(Y)和性质(UY)

Properties(Y) and (UY) for Bounded Linear Operators

引入Weyl型定理的两种新的谱性质:性质(Y)和性质(UY),探讨这两种性质与其它Weyl型定理之间的关系.

In this paper, we introduce two new spectral properties （Y） and （UY） in connec- tion with Weyl type theorems, and study the relationships of these two properties with other Weyl type theorems.
