Weighted composition operators from Bergman-type spaces into Bloch spaces
Let D be the open unit disk in the complex plane C. Denote by H(D) the class of all functions analytic on D. An analytic self-map φ : D → D induces the composition operator Cφ on H(D), defined by Cφ ( f ) = f (φ(z)) for f analytic on D. It is a well-known consequence of Littlewood’s subordination principle that the composition operator Cφ is bounded on the classical Hardy and Bergman spaces (se...
متن کاملWeighted composition operators on weighted Bergman spaces and weighted Bloch spaces
In this paper, we characterize the bonudedness and compactness of weighted composition operators from weighted Bergman spaces to weighted Bloch spaces. Also, we investigate weighted composition operators on weighted Bergman spaces and extend the obtained results in the unit ball of $mathbb{C}^n$.
متن کاملThe Bergman Spaces, the Bloch Space, and Gleason's Problem
Suppose / is a holomorphic function on the open unit ball Bn of Cn. For 1 < p < oo and to > 0 an integer, we show that / is in Lp(Bn,dV) (with dV the volume measure) iff all the functions dmf/dza (\a\ = to) are in Lp(Bn,dV). We also prove that / is in the Bloch space of Bn iff all the functions dmf/dza (\a\ = m) are bounded on Bn. The corresponding result for the little Bloch space of Bn is est...
متن کاملRiemann-Stieltjes operators between Bergman-type spaces and α-Bloch spaces
We study the following integral operators: J g f (z)= z 0 f (ξ)g (ξ)dξ; I g f (z)= z 0 f (ξ)g(ξ)dξ, where g is an analytic function on the open unit disk in the complex plane. The bounded-ness and compactness of J g , I g between the Bergman-type spaces and the α-Bloch spaces are investigated.
متن کاملComposition Operators between Bergman and Hardy Spaces
We study composition operators between weighted Bergman spaces. Certain growth conditions for generalized Nevanlinna counting functions of the inducing map are shown to be necessary and sufficient for such operators to be bounded or compact. Particular choices for the weights yield results on composition operators between the classical unweighted Bergman and Hardy spaces.
