摘要
利用 Ditzian模ω2φλ( f ,t) ( 0≤λ≤ 1 )研究了 Sikkema算子导数与它所逼近函数光滑性之间关系 ,得到了 Sikkema算子导数与
Use the Ditzian modulous of smoothness ω 2 φλ(f,t)(0≤λ≤1) to study the relation of the derivatives between Sikkema operators and the smoothness of the function it approximate, and a direct theorem between Sikkema operators and the Ditzian modulous of smoothness is obtained.
