摘要

以定量形式证明了极大Bergman投影 \begin{equation*} P^{+}_\omega(f)(z)=\int_\mathbb{D} f(\zeta)|B^\omega_z(\zeta)|\omega(\zeta)\,dA(\zeta), \end{equation*} 从LνpL^p_\nuLηpL^p_\eta有界当且仅当 \begin{equation*} \sup_{0<r<1}\left(\int_0^r\frac{\eta(s)}{\left(\int_{s}^1\omega(t)\,dt\right)^p}\,ds\right)^{\frac{1}{p}} \left(\int_r^1\left(\frac{\omega(s)}{\nu(s)^\frac{1}{p}}\right)^{p'}ds\right)^{\frac{1}{p'}}<\infty, \end{equation*} 其中ω,ν,η\omega,\nu,\eta为径向正则权。径向权σ\sigma是正则的,若对所有0r<10\leq r<1满足σ(r)r1σ(t)dt/(1r)\sigma(r)\asymp\int_{r}^1\sigma(t)\,dt/(1-r)。还证明了在涉及ω\omegaη\eta的适当附加假设下,Bergman投影PωP_\omegaPω+P^+_\omega同时有界。
