Abstract
In this paper, by using the Ditzian - Totik modulusω(?)'λ(f;t) we study the relationship between the derivatives of the linear combinations of the Szasz - type operators and the smoothness of the function the linear combinations of the Szasz -type operators approximates to. We've got the equivalent theorem between the derivatives of the linear combinations of the Szasz - type operators and the Ditzian - Totik modulus.
