摘要设VM*(0,2π)记为周期为2π的广义囿变函数空间,CVM*(0,2π)记为VM*(0,2π)空间所有连续函数类。本文的主要结果是; 若f∈CVM*(0,2π),以及M满足△2条件,则存在常数A>0,λ>0有En(f;λ)VM≤4/n sum from μ-1 to n+1 ωVM(F;X/μ,λ)其中En(f,λ)VM和ωVM(f;h,λ
Abstract:Let VM*(0,2π) denote the Space of functions of 2π--periodic generalizedvariations in a compact interval (0,2M) Let cv*.(0,2π) denote The class of allcontinuous fuctions in the VM* (0,2π) space. The following main result is obtained:If fεCVM*
