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 Ces\`aro-like operator is defined by Cμ(f)(z)=n=0(μnk=0nak)zn, zD, \mathcal {C}_{\mu} (f)(z)=\sum^\infty_{n=0}\left(\mu_n\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). Let XX and YY be subspaces of H(D)H( \mathbb{D}), the purpose of this paper is to study the action of Cμ\mathcal {C}_{\mu} on distinct pairs (X,Y)(X, Y). The spaces considered in this paper are Hardy space Hp(0<p)H^{p}(0<p\leq\infty), Morrey space L2,λ(0<λ1)L^{2,\lambda}(0<\lambda\leq1), mean Lipschitz space, Bloch type space, etc.
