TY - JOUR AU - Xiao Ming Zeng PY - 2011/11/25 Y2 - 2024/03/28 TI - Approximation for absolutely continuous functions by Stancu Beta operators JF - Ukrains’kyi Matematychnyi Zhurnal JA - Ukr. Mat. Zhurn. VL - 63 IS - 11 SE - Short communications DO - UR - https://umj.imath.kiev.ua/index.php/umj/article/view/2827 AB - In this paper, we obtain an exact estimate for the first-order absolute moment of Stancu Beta operators by means of the Stirling formula and integral operations. Then we use this estimate for establishing a theorem on approximation of absolutely continuous functions by Stancu Beta operators. ER -
