Quantitative estimates for a certain bivariate Chlodowsky-Szasz-Kantorovich type operators

Nurhayat İspir, İbrahim Büyükyazıcı


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