我们刻画了在可分Hilbert空间上,对于$1<p<\infty$,算子加权的$L^p$空间上的Bergman投影的有界性。在方向可积性条件下,判据是单位圆盘中Carleson方块上平均的一致有界性。我们获得了与维数无关的范数估计。证明使用了分离核展开和帐篷树的层分解。不需要反向Hölder假设。我们还给出了一个带有维数相关常数的更精细的矩阵估计。有界性在保持可积性条件的紧支撑权重变化下不变。
英文摘要
We characterize boundedness of the Bergman projection on operator-weighted $L^p$ spaces over a separable Hilbert space, for $1<p<\infty$. Under the directional integrability conditions, the criterion is uniform boundedness of averages over Carleson squares in the unit disc. We obtain norm estimates independent of dimension. The proof uses a separated kernel expansion and a layer decomposition of the tent tree. No reverse Hölder assumption is needed. We also give a finer matrix estimate with a dimension-dependent constant. Boundedness is unchanged by compactly supported changes of the weight that preserve the integrability conditions.
