On Some Normality-Like Properties and Bishop's Property (𝛽) for a Class of Operators on Hilbert Spaces
We prove some further properties of the operator 𝑇∈[𝑛QN] (𝑛-power quasinormal, defined in Sid Ahmed, 2011). In particular we show that the operator 𝑇∈[𝑛QN] satisfying the translation invariant property is normal and that the operator 𝑇∈[𝑛QN] is not supercyclic provided that it is not invertible. Als...
