Abstract

For λ0, a C2 function f defined on the unit disk D is said to be λ-analytic if Dz̄f=0, where Dz̄ is the (complex) Dunkl operator given by Dz̄f=z̄fλ(f(z)f(z̄))/(zz̄). The aim of the paper is to study several problems on the associated Bergman spaces Aλp(D) and Hardy spaces Hλp(D) for p2λ/(2λ+1), such as boundedness of the Bergman projection, growth of functions, density, completeness, and the dual spaces of Aλp(D) and Hλp(D), and characterization and interpolation of Aλp(D).

与一类广义解析函数相关的伯格曼和哈代空间的某些方面
对于λ≥0,如果Dz̄f=0,则定义在单位圆盘D上的C2函数f被称作是λ解析的,其中Dz̄是由Dz̄f=∂z̄f-λ(f(z)-f(z̄))/(z-z̄)给出的(复)Dunkl算子。本文旨在研究 p≥2λ/(2λ+1) 时相关伯格曼空间 Aλp(D) 和哈代空间 Hλp(D) 的若干问题,如伯格曼投影的有界性、函数的增长、密度、完备性以及 Aλp(D) 和 Hλp(D) 的对偶空间,以及 Aλp(D) 的表征和插值。

期刊介绍: The Journal of Approximation Theory is devoted to advances in pure and applied approximation theory and related areas. These areas include, among others: • Classical approximation • Abstract approximation • Constructive approximation • Degree of approximation • Fourier expansions • Interpolation of operators • General orthogonal systems • Interpolation and quadratures • Multivariate approximation • Orthogonal polynomials • Padé approximation • Rational approximation • Spline functions of one and several variables • Approximation by radial basis functions in Euclidean spaces, on spheres, and on more general manifolds • Special functions with strong connections to classical harmonic analysis, orthogonal polynomial, and approximation theory (as opposed to combinatorics, number theory, representation theory, generating functions, formal theory, and so forth) • Approximation theoretic aspects of real or complex function theory, function theory, difference or differential equations, function spaces, or harmonic analysis • Wavelet Theory and its applications in signal and image processing, and in differential equations with special emphasis on connections between wavelet theory and elements of approximation theory (such as approximation orders, Besov and Sobolev spaces, and so forth) • Gabor (Weyl-Heisenberg) expansions and sampling theory.
