Summary

Introduction and Main Results

A function ω : D Ñ r0, 8q, integrable over the unit disc D, is called a weight. It is radial if ωpzq “ ωp|z|q for all z P D. The most commonly known result on Bergman projection is due to Bekolleand Bonami [3, 4], and concerns the case when ν “ η is an arbitrary weight and the inducing weight ω is standard, that is, of the form ωpzq “ p1 ́ |z|2qα for some α ą1; see [1, 11, 13] for recent extensions of this result. In this classical case, the Bergman reproducing kernel Bzωpζ q is given by the neat formula p1 ́ zζ qp2`αq. If a À b and a Á b, we will write a — b
