We establish characterizations of the radial weights ω on the unit disc such that the Bergman projection , induced by ω, is bounded and/or acts surjectively from to the Bloch space , or the dual of the weighted Bergman space is isomorphic to the Bloch space under the -pairing. We also solve the problem posed by Dostanić in 2004 of describing the radial weights ω such that is bounded on the Lebesgue space , under a weak regularity hypothesis on the weight involved. With regard to Littlewood-Paley estimates, we characterize the radial weights ω such that the norm of any function in is comparable to the norm in of its derivative times the distance from the boundary. This last-mentioned result solves another well-known problem on the area. All characterizations can be given in terms of doubling conditions on moments and/or tail integrals of ω, and are therefore easy to interpret.

径向权重引起的伯格曼投影
我们在单位圆盘上建立径向权重ω 的特征,使得伯格曼投影,由ω诱导,有界和/或从 到布洛赫空间 ,或加权伯格曼空间的对偶 与 Bloch 空间同构 -配对。我们还解决了 Dostanić 在 2004 年提出的描述径向权重ω 的问题,使得 在 Lebesgue 空间上有界 ,在所涉及的权重的弱规律性假设下。关于 Littlewood-Paley 估计,我们刻画径向权重ω,使得任何函数的范数在 与标准中的标准相当 其导数乘以到边界的距离。最后提到的这个结果解决了该地区另一个众所周知的问题。所有特征都可以根据矩和/或尾积分的加倍条件给出的ω,因此是很容易理解。
