Approximation properties and q-statistical convergence of Kantorovich variant of Stancu type Lupas operators

Abstract

We introduce Kantorovich variant of Stancu-Lupas operators and study convergence and qstatistical convergence properties using Korovkin theorem. Rate of convergence is analyzed in terms of modulus of continuity, elements of Lipschitz class and Peetre’s K-functional. Direct theorems are proved and Voronovskaja type theorem is established. Graphical analysis of convergence and error estimations are presented with the help of MATLAB.
