Abstract

Let ω\omega be a radial weight, 0<p,q<0<p,q<\infty and Γ(ξ)={zD:argzargξ<(ξz)}\Gamma(\xi)=\left\{z\in\mathbb{D}:|\arg z-\arg\xi|<(|\xi|-|z|)\right\} for ξD\xi\in\overline{\mathbb{D}} . The average radial integrability space Lpq(ω)L^q_p(\omega) consists of complex-valued measurable functions ff on the unit disc D\mathbb{D} such that fLpq(ω)q=12π02π(01f(reiθ)pω(r)rdr)qpdθ<,\|f\|^q_{L^q_p(\omega)}=\frac{1}{2\pi}\int_{0}^{2\pi}\left(\int_{0}^{1}|f(re^{i\theta})|^p\omega(r)r\,dr\right)^{\frac{q}{p}}d\theta <\infty, and the tent space Tpq(ω)T^q_p(\omega) is the set of those ff for which fTpq(ω)q=12πD(Γ(ξ)f(z)pω(z)dA(z)1z)qpdξ<.\|f\|^q_{T_{p}^{q}(\omega)}=\frac{1}{2\pi}\int_{\partial{\mathbb{D}}}\left(\int_{\Gamma(\xi)}|f(z)|^p\omega(z)\frac{dA(z)}{1-|z|}\right)^{\frac{q}{p}}\,|d\xi|<\infty. Let H(D)\mathcal{H}(\mathbb{D}) denote the space of analytic functions in D\mathbb{D}. It is shown that the non-tangential maximal operator fN(f)(ξ)=supzΓ(ξ)f(z),ξD,f\mapsto N(f)(\xi)=\sup_{z\in\Gamma(\xi)}|f(z)|,\quad \xi\in \mathbb{D}, is bounded from ALpq(ω)=Lpq(ω)H(D)AL^q_p(\omega)=L^q_p(\omega)\cap\mathcal{H}(\mathbb{D}) and ATpq(ω)=Tpq(ω)H(D)AT^q_p(\omega)=T^q_p(\omega)\cap\mathcal{H}(\mathbb{D}) to Lpq(ω)L^q_p(\omega) and Tpq(ω)T^q_p(\omega), respectively. These pivotal inequalities are used to establish further results such as the density of polynomials in ALpq(ω)AL^q_p(\omega) and ATpq(ω)AT^q_p(\omega), and the identity ALpq(ω)=ATpq(ω)AL^q_p(\omega)=AT^q_p(\omega) for weights admitting a one-sided integral doubling condition. It is also shown that the boundedness of the classical Bergman projection PγP_\gamma, induced by the standard weight (γ+1)(1z2)γ(\gamma+1)(1-|z|^2)^{\gamma}, on Lpq(ω)L^q_p(\omega) and Tpq(ω)T^q_p(\omega) with 1<q,p<1<q,p<\infty is independent of qq, and is described by a Bekoll\'e-Bonami type condition.
