摘要：

We study (C-p, alpha)-normal operators and (Cp, alpha)-hyponormal operators. We show the inclusion relation between these classes under various hypotheses for p and a. We also obtain some sufficient conditions for Aluthge transform (T) over tilde (s,t) = vertical bar T vertical bar U-s vertical bar T vertical bar(t) and T-2 of (C-p, alpha)-hyponormal operators still to be (C-p, alpha)-hyponormal.
