On the order of weighted approximation by positive linear operators

Authors: TÜLİN COŞKUN

Abstract: An estimation of approximation of continuous functions by positive linear operators in weighted norm using the weighted modulus of continuity is established. Application of the main result to the known Gadjiyev-Ibragimov operators is given.

Keywords: Positive linear operators, weighted spaces, weighted modulus of continuity, Korovkin type theorems, Gadjiev-Ibragimov operators
