Quantitative Estimates for GBS Operators of Chlodowsky-Szász Type

Nurhayat Ispir

In this study we construct the GBS (Generalized Boolean Sum) operators associated with combination of Chlodowsky and modified Szász operators and estimate the degree of approximation for these operators in terms of the mixed (Bögel) modulus of smoothness. Furthermore, we improve the measure of smoothness by the mixed $K$-functional.
