摘要：
Let T be a p-hyponormal operator on a Hilbert space with polar decomposition T = U\T\ and let (T) over tilde = \T\U-t\T\(r-t) for r > 0 and r greater than or equal to t greater than or equal to 0. We study order and spectral properties of T. In particular we refine recent Furuta's result on p-hyponormal operators.
