Abstract: |
In this paper, we discuss the judgement conditions that A∈B(H)N is the operator point spectrum of T∈B(H) . In particular, a condition is given for A∈Λp(T) when T is a hyponormal operator and A is commutable for T and T*. Additionally, we obtain the judgement condition forkerτnT,A=kerτT,A. |
