Let f= P[F] denote the Poisson integral of F in the unit disk D with F being absolutely continuous in the unit circle T and F˙ ∈ Lp(T) , where F˙(eit)=ddtF(eit) and p≥ 1. Recently, the author in Zhu (J Geom Anal, 2020) proved that (1) if f is a harmonic mapping and 1 ≤ p< 2 , then fz and fz¯¯ ∈ Bp(D) , the classical Bergman spaces of D [12, Theorem 1.2]; (2) if f is a harmonic quasiregular mapping and 1 ≤ p≤ ∞, then fz, fz¯¯ ∈ Hp(D) , the classical Hardy spaces of D [12, Theorem 1.3]. These are the main results in Zhu (J Geom A...
