Abstract

Let ω\omega be a radial weight on the unit disc of the complex plane D\mathbb{D} and denote ωx=01sxω(s)ds\omega_x =\int_0^1 s^x \omega(s)\,ds, x0x\ge 0, for the moments of ω\omega and ω^(r)=r1ω(s)ds\widehat{\omega}(r)=\int_r^1 \omega(s)\,ds for the tail integrals. A radial weight ω\omega belongs to the class D^\widehat{\mathcal{D}} if satisfies the upper doubling condition sup0<r<1ω^(r)ω^(1+r2)<.\sup_{0<r<1}\frac{\widehat{\omega}(r)}{\widehat{\omega}\left(\frac{1+r}{2}\right)}<\infty. If ν\nu or ω\omega belongs to D^\widehat{\mathcal{D}}, it is described the boundedness of the Bergman projection PωP_\omega induced by ω\omega on the growth space Lν^={f:f,v=esssupzDf(z)ν^(z)<}L^\infty_{\widehat{\nu}} =\{ f: \|f\|_{\infty,v}={ esssup}_{z\in\mathbb{D}} |f(z)|\widehat{\nu}(z)<\infty\} in terms of neat conditions on the moments and/or the tail integrals of ω\omega and ν\nu. Moreover, it is solved the analogous problem for PωP_\omega from Lν^L^\infty_{\widehat{\nu}} to the Bloch type space Bν^B^\infty_{\widehat{\nu}} of analytic functions such that supzD(1z)ν^(z)f(z)<.\sup_{z\in \mathbb{D}}(1-|z|)\widehat{\nu}(z) |f'(z)|<\infty. We also study similar questions for exponentially decreasing radial weights.
