In this note,using some results of the probability theory we obtained some estimates ofthe approximation of classes or functions for modified Szasz operators wi
In this paper,we study a special class of fractal interpolation functions,and give theirHaar-wavelet expansions.On the basis of the expansions,we investigate th
Let p<sub>n</sub>(z)=∑<sub>k-0</sub><sup>n</sup> a<sub>k</sub>z<sup>k</sup> be a polynomial of degree n such that |p<sub>n</sub>(z)|≤M for |z|≤1. It is well.know
