On Hardy spaces on worm domains

open access: yesConcrete Operators, 2016
In this review article we present the problem of studying Hardy spaces and the related Szeg˝o projection on worm domains. We review the importance of the Diederich–Fornæss worm domain as a smooth bounded pseudoconvex domain whose Bergman projection does ...

𝐿^{𝑝} regularity of weighted Bergman projections [PDF]

open access: yesTransactions of the American Mathematical Society, 2012
We investigate L p L^p regularity of weighted Bergman projections on the unit disc and L p L^p regularity of ordinary Bergman projections in higher dimensions.

On the boundedness of Bergman projection [PDF]

open access: yesAdvanced Courses of Mathematical Analysis VI, 2016
The main purpose of this survey is to gather results on the boundedness of the Bergman projection. First, we shall go over some equivalent norms on weighted Bergman spaces $A^p_\omega$ which are useful in the study of this question. In particular, we shall focus on a decomposition norm theorem for radial weights~$\omega$ with the doubling property ...

Finite-rank intermediate Hankel operators on the Bergman space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Let L2=L2(D,r dr dθ/π) be the Lebesgue space on the open unit disc and let La2=L2∩ℋol(D) be the Bergman space. Let P be the orthogonal projection of L2 onto La2 and let Q be the orthogonal projection onto L¯a,02={g∈L2;g¯∈La2,   g(0)=0}. Then I−P≥Q.

Projective generators inHardy and Bergman spaces

open access: yesBulletin des Sciences Mathématiques, 2000
A function \(f\) in the Bergman space \(A^2\) (respectively, the Hardy space \(H^2)\) is called a projective generator of defect \(n\) if \[ \text{codim}_{[g]} [P_{[g]}f]\leq n \] for any \(g\in A^2\) (respectively, \(H^2)\) such that \(P_{[g]}f\neq 0\), and if equality holds for some \(g\).

A Sharp Constant for the Bergman Projection [PDF]

open access: yesCanadian Mathematical Bulletin, 2015
AbstractFor the Bergman projection operator P we prove thatHere λ stands for the hyperbolic metric in the unit ball B of Cn, and B1 denotes the Besov space with an adequate semi-norm. We also consider a generalization of this result. This generalizes some recent results due to Perälä.

On estimates for weighted Bergman projections [PDF]

open access: yesProceedings of the American Mathematical Society, 2015
In this note we show that the weighted $L^{2}$-Sobolev estimates obtained by P. Charpentier, Y. Dupain & M. Mounkaila for the weighted Bergman projection of the Hilbert space $L^{2}\left( ,d _{0}\right)$ where $ $ is a smoothly bounded pseudoconvex domain of finite type in $\mathbb{C}^{n}$ and $ _{0}=\left(- _{0}\right)^{r}d $, $ $ being the

Sharp Békollé estimates for the Bergman projection

open access: yesJournal of Functional Analysis, 2013
We prove sharp estimates for the Bergman projection in weighted Bergman spaces in terms of the Bekolle constant. Our main tools are a dyadic model dominating the operator and an adaptation of a method of Cruz-Uribe, Martell and Perez.

ON SOME NEW PROJECTION THEOREMS AND SHARP ESTIMATES IN HERZ TYPE SPACES IN BOUNDED PSEUDOCONVEX DOMAINS [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2018
We prove new projection theorems for new Herz type spaces in various domains in Cn in the unit disk, unit ball, bounded pseudoconvex domains and based on these results we provide sharp estimates for distances in such type spaces under one condition on ...
