Abstract:
It is known that the square of a w-hyponormal operator is also w-hyponormal. For any 00, 0characterization of (s,p)-w-hyponormal operators; the author shows that all integer powers of special (s,p)-w-hyponormal operators are (s,p)-w-hyponormal.
Key words: Furuta inequality, Lowner-Heinz inequality, p-w-hyponormal, (s,p)-w-hyponormal
