In this paper, we discuss the boundedness of the composition operator T1,φ and weighted composition operator Tψ,φ from Hardy space H∞ to p-Bloch space βp on the unit disc, and obtain the sufficient and necessary condition. We study the pointwise multipliers from space β0p to H∞ on the unit disc and the compactness of T1,φ from space β0p to β0q. We consider the boundedness of the composition operator T1,φ from H∞ to little p-Bloch space, and obtain the sufficient and necessary condition. |
