报告摘要：
We characterize those radial weights that induce the Bergman projection mapping the space of continuous functions in the closed unit disc boundedly into the little Bloch space. We also characterize the weights for which the projection is onto. The proofs are different from those used in the case of standard radial weights and are based on a new pointwise estimate of the modulus of the Bergman reproducing kernel induced by a radial doubling weight.
