Weyl型定理及其摄动

Weyl Type Theorem and Perturbations

利用算子A的解析部分以及拟幂零部分,研究了A的Weyl型定理和Weyl型定理摄动的稳定性.还讨论了一些重要的Banach空间算子的Wleyl型定理.

Using the analytic core we study Weyl type theorem for A and the quasi-nilpotent part In additional, we study the theorem under perturbations by operators in some known classes in an important class of Banach space operators is also studied. of an operator A, stability of Weyl＇s Weyl type theorem
