We study smoothing properties of the Bergman projection and weighted projections. In particular, we relate these to hyperconvexity index a pseudoconvex domain in C n . The notion was first introduced by B.Y. Chen, which provides flexible criterion for studying geometric hyperconvex domains. also obtain new estimate projections, extends well-known Berndtsson Charpentier. then give some applicati...

We obtain some new uniform estimates and maximal theorems in classical Hardy spaces the unit disk related with Bergman projection, thus extending previously well-known inequalities on spaces.

1.1. Definitions Throughout this paper, λ denotes the Lebesgue measure on C and ωo = dd|z| the Euclidean Kähler form in C, where d = √ −1 4 (∂̄ − ∂). Let φ ∈ C (C) be a function, μ a measure in C, and p ∈ [1,∞). One can define the spaces Lp(e−pφdμ) and F (μ, φ) := Lp(e−pφdμ) ∩ O(C). If the measure μ is Lebesgue measure, we simply write F (λ, φ) =: F (φ). Similarly one can define L∞(e−φ, μ) = {f ...

We construct higher-dimensional versions of the Diederich-Fornæss worm domains and show that the Bergman projection operators for these domains are not bounded on high-order Lp-Sobolev spaces for 1 ≤ p < ∞.
