Abstract

Let p > 1 and α[p](x) : $\sqrt{x}$, $\sqrt{\frac{p}{^2p-1}}$, $\sqrt{\frac{2p-1}{3p-2}}$, … , with 0 < x ≤ $\frac{p}{2p-1}$. In [10], the authors considered the subnormality, n-hyponormality and positive quadratic hyponormality of Wα[p](x). By continuing to study, in this paper, we give a sufficient condition of quadratic hyponormality of Wα[p](x). Finally, we give an example to characterize the gaps of Wα[p](x) distinctively.
