摘要
本注记在文献[1 ]的基础上进一步讨论了算子A∈B(H) N 为算子T∈B(H)的算子点谱的特征 特别得到当T为亚正常算子、A与T及T 可换时A为T的算子点谱的充要条件 同时得到了KerτnT ,A=KerτT 。
In this remark, we discuss the characte that A∈B(H) N is the operator point spectrum of T∈B(H) In particular, when T is a hyponormal operator and A is commutable for T and T a sufficient condition and necssary condition was obtained Additionally, we obtained the sufficient condition and necessary condition for ker τ n T,A =kerτ T,A
