Trace theorems in harmonic function spaces on (R^n+1)^m,multiplier theorems and related problems
We introduce and study properties of certain new harmonic function spaces on
products of upper half-spaces.Norm estimates for the so-called expanded Bergman
projections are obtained.Sharp theorems on multipliers acting on certain
Sobolev type spaces of harmonic functions on the unit ball are also obtainedComment: 17 page
Some remarks on extremal problems in weighted Bergman spaces of analytic functions
We prove some sharp extremal distance results for functions in weighted
Bergman spaces on the upper halfplane.We also prove such results in the context
of bounded strictly pseudoconvex domains with smooth boundar
On Embeddings,Traces and Multipliers in harmonic function spaces
This paper is devoted to certain applications of classical Whitney
decomposition of the upper half space R^n+1 to various problems in harmonic
function spaces in the upper half space.We obtain sharp new assertions on
embeddings,distances and traces for various spaces of harmonic functions New
sharp theorems on multipliers for harmonic function spaces in the unit ball are
also presented .Comment: 17 page

A note on Fefferman-Stein type characterizations for certain spaces of analytic functions in the unit disk
We obtain new characterizations of Bergman and Bloch spaces on the unit disc
involving equivalent (quasi)-norms of these spaces.Our results are in spirit of
estimates obtained by Fefferman and Stein for HArdy spaces in R^n.Comment: 5 page

On an extremal problem in analytic function spaces in tube domains over symmetric cones
New sharp estimates concerning distance function in Bergman - type analytic
function spaces on tube domains over symmetric cones are obtained. These are

Embedding relations and boundedness of the multifunctional operators in tube domains over symmetric cones
We obtain a new general sufficient condition for the continuity of the
Bergman projection in tube domains over symmetric cones using multifunctional
embeddings.We also obtain some sharp embedding relations between the
generalized Hilbert-HArdy spaces and the mixed norm Bergman spaces in this
setting.Comment: 16 page
