Abstract
In this paper, we consider vector-valued Bergman–Orlicz spaces which are generalization of classical vector-valued Bergman spaces. We characterize the dual space of vector-valued Bergman–Orlicz space, and study the boundedness of the little Hankel operators, \(h_b\), with operator-valued symbols b, between different weighted vector-valued Bergman–Orlicz spaces on the unit ball \(\mathbb{B}_n\).More precisely, given two complex Banach spaces X, Y, we characterize those operator-valued symbols\(b \colon \mathbb{B}_n\rightarrow \mathcal{L} (\overline{X},Y) \) for which the little Hankel operator \(h_{b}: A^{\Phi_{1}}_{\alpha}(\mathbb{B}_{n},X) \longrightarrow A^{\Phi_{2}}_{\alpha}(\mathbb{B}_{n},Y)\), extends into a bounded operator, where \(\Phi_{1}\) and \(\Phi_2\) are either convex or concave growth functions.
