Research output: Contribution to journalArticlepeer-review


For any f∈ Hp(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 Hq(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.
