Weighted Approximation of Continuous Functions by Sequences of Linear Positive Operators

[摘要] In this work we obtain, under suitable conditions, theorems of Korovkin type for spaces with different weight, composed of continuous functions defined on unbounded regions. These results can be seen as an extension of theorems by Gadjiev in [4] and [5].
