Abstract

In this paper we give direct, inverse, and equivalence approximation theorems with unified Ditzian-Totik modulus [image omitted] (0 ≤ λ ≤ 1) for Meyer-Konig and Zeller operators. [ABSTRACT FROM AUTHOR]

Abstract

Recently some classical operator quasi-interploants were introduced to obtain much faster convergence. P. Mache and D. H. Mache gave Bernstein quasi-interpolants and obtained approximation equivalence theorem with . In this article we extend above result with modulus which unified classical modulus and Ditzian-Totik modulus. [ABSTRACT FROM AUTHOR]
