Abstract

Let μ\mu be a positive Borel measure on the interval [0,1)[0,1). The Hankel matrix Hμ=(μn,k)n,k0\mathcal{H}_{\mu}=(\mu_{n,k})_{n,k\geq 0} with entries μn,k=μn+k\mu_{n,k}=\mu_{n+k}, where μn=[0,1)tndμ(t)\mu_{n}=\int_{[0,1)}t^nd\mu(t), induces, formally, the Derivative-Hilbert operator DHμ(f)(z)=n=0(k=0μn,kak)(n+1)zn, zD,\mathcal{DH}_\mu(f)(z)=\sum_{n=0}^\infty\left(\sum_{k=0}^\infty \mu_{n,k}a_k\right)(n+1)z^n , ~z\in \mathbb{D}, where f(z)=n=0anznf(z)=\sum_{n=0}^\infty a_nz^n is an analytic function in D\mathbb{D}. We characterize the measures μ\mu for which DHμ\mathcal{DH}_\mu is a bounded operator on BMOABMOA space. We also study the analogous problem from the α\alpha-Bloch space Bα(α>0)\mathcal{B}_\alpha(\alpha>0) into the BMOABMOA space.
