We study the boundedness of the linear operator S on L^p₀ (dA) ~ (0<p<). In particular, we obtain a sufficient and necessary condition for the compactness of the linear operator S on L^p₀ (dA) ~ (1<p<). Our results weaken the assumptions of earlier results of J. Miao and D. Zheng in a certain sense.
Lou et al. (Mon,) studied this question.
