Isolated points of spectrum of (p, k)-quasihyponormal operators
TL;DR: In this article, it was shown that if λ 0 is an isolated point of σ(T), then E is self-adjoint and EH =ker(T−λ 0)∗, then EH=ker( Tk).
Journal ArticleDOI

Muneo Chō,Takeaki Yamazaki +1 more
TL;DR: In this article, an operator transform from class A to the class of hyponormal operators was given, and it was shown that every class A operator has SVEP and property β.
Journal ArticleDOI
On Aluthge Transforms of p-hyponormal Operators
TL;DR: In this article, the authors give an example of an ∞-hyponormal operator T whose Aluthge transform is not (1+√ + √)-hyponorm for any ǫ > 0 and show that the sequence of inter-aluthge transforms of T need not converge in weak operator topology.
