Approximation by Left Quasi-interpolants of Derivatives of Gamma Operators
摘要/Abstract
摘要:
为了得到更快的逼近速度,引入了某些著名算子的拟中插式.在前人研究的基础上,借助于Ditzian-Totick光滑模ω2rφλ(f,t)∞,给出了Gamma算子导数左拟中插式的逼近点态结果。
Abstract:
Recently Müller introduced the left Gamma quasi-interpolants and obtainedan approximation equivalence theorem with ω2rφ(f,t)p.Guo extended the results with ω2rφλ(f,t)∞.A approximation equivalence theorem is given with ω2rφλ(f,t)∞ which unified classical modulus and Ditzian-Totick modulus and improve the previous resluts.
