二元高阶Lipschitz函数类和二重Fourier级数
The double higher Lipschitz classes and the double Fourier series
摘要
Abstract
We introduce the higher order double Lipschitz classes of functions ∧r,s(ω) and λr,s (ω) by means of the double (R,S) th difference operator and modulus of continuity. We obtain sufficient and necessary conditions in terms of the coefficients for f∈∧r,s (ω) and f∈λr,s (ω).关键词
