摘要

For any f∈ H^p(D) (p> 0) , the Hardy space over the unit disk, we characterize completely the triple (α, p, q) ∈ (- 1 , ∞) × (0 , ∞) ² such that the Cesàro partial sum σnαf converges in norm in H^q(D) , and in the Bergman space Laq(D) , respectively. This extends recent results of McNeal–Xiong and of Park–Zhao–Zhu, and complements a classical theorem of Hardy-Littlewood in 1934.
