4. Pointwise approximation by Baskakov quasi-interpolants

Author

Guo, Shunsheng, Qi, Qiulan, and Liu, Lixia

Subjects
*INTERPOLATION, *OPERATOR theory, *APPROXIMATION theory, *EQUIVALENCE relations (Set theory), *MODULES (Algebra)
Abstract

Abstract: Recently, the quasi-interpolants of some classical operators were introduced. Mache and Müller gave Baskakov quasi-interpolants and obtained approximation equivalence theorem with In this paper, we extend the above result with modulus (0 ≤ λ ≤ 1) which unified classical modulus and Ditzian-Totik modulus.
