Abstract

Let μ\mu be a finite positive Borel measure on the interval [0,1)[0,1) and f(z)=n=0anznH(D)f(z)=\sum_{n=0}^{\infty}a_{n}z^{n} \in H(\mathbb{D}). The Ce\`{a}sro-like operator is defined by Cμ(f)(z)=n=0μn(k=0nak)zn, zD, \mathcal{C}_\mu(f)(z)=\sum^\infty_{n=0}\mu_n\left(\sum^n_{k=0}a_k\right)z^n, \ z\in \mathbb{D}, where, for n0n\geq 0, μn\mu_n denotes the nn-th moment of the measure μ\mu, that is, μn=[0,1)tndμ(t)\mu_n=\int_{[0, 1)} t^{n}d\mu(t). In this paper, we characterize the measures μ\mu for which Cμ\mathcal{C}_\mu is bounded (compact) from one Bloch type space, Bα\mathcal {B}^{\alpha}, into another one, Bβ\mathcal {B}^{\beta}.
