Özet

In this paper, we introduce a bivariate Kantorovich variant of the combination of Chlodowsky and Szasz type operators and study local approximation properties of these operators. We estimate the approximation order in terms of Peetre's K-functional and partial moduli of continuity. We also give some numerical error estimates and illustrations.
