q-moduli of Smoothness and Hardy-Littlewood Type Theorem in Mixed Norm Spaces

摘要/Abstract

摘要:

研究了混合模空间中全纯函数的逼近性质与其边界函数值的光滑性的密切关系.采用q光滑模得出Jackson定理、q光滑模与本性K泛函的等价性,并在混合模空间中借助K泛函获得关于导数增长的Hardy-Littlewood定理和强逆估计.

Abstract:

Some aspects of the interplay between approximation properties of holomorphic functions in mixed norm spaces and the smoothness of its boundary values are discussed.We obtain Jackson theorem and the equivalence of a special qmodulus of smoothness and an intrinsic Kfunctional.Further,a generalization of HardyLittlewood theorem on the growth of derivatives and strong converse estimates are deduced by using Kfunctional in mixed norm spaces .
