Differences of operators of generalized Szász type

[摘要] We derive the approximation of differences of operators. Firstly, we study quantitative estimates for the difference of generalized  Szász operators with generalized Szász-Durrmeyer, Szász-Puãltvänea  operators, and generalized Szász--Kantorovich operators. Finally, we obtain the quantitative estimate in terms of the weighted modulus of smoothness for these operators.
