Abstract:
We consider the Hilbert-type operator defined by Hω(f)(z)=∫10f(t)(1z∫z0Bωt(u)du)ω(t)dt,
where {Bωζ}ζ∈D are the reproducing kernels of the Bergman space A2ω induced by a radial weight ω in the unit disc D. We prove that Hω is bounded from H∞ to the Bloch space if and only if ω belongs to the class ˆD, which consists of radial weights ω satisfying the doubling condition sup0≤r<1∫1rω(s)ds∫11+r2ω(s)ds<∞. Further, we describe the weights ω∈ˆD such that Hω is bounded on the Hardy space H1, and we show that for any ω∈ˆD and p∈(1,∞), Hω:Lp[0,1)→Hp is bounded if and only if the Muckenhoupt type condition sup0<r<1(1+∫r01ˆω(t)pdt)1p(∫1rω(t)p′dt)1p′<∞,
holds. Moreover, we address the analogous question about the action of Hω on weighted Bergman spaces Apν.
