L~p空间有理插值型算子的逼近(英文)
Approximation of Rational Interpolation Type Operators in Lp Spaces
【摘要】 考虑了两类有理插值型算子的Jackson型估计.当p>1时,建立了Dilzian-Totik型定理,当p=1时,利用通常连续模给出了Jackson型估计.
【Abstract】 The present paper considers to establish Jackson type estimates for two kinds of rational interpolation operators. A Ditzian-Totik type theorem is obtained for p>1. For p=1, we give a Jackson estimate by using the usual modulus of continuity.
