On Stancu-type generalization of modified \((p,q)\)-Szász-Mirakjan-Kantorovich operators
Summary: In the present article, we construct \((p,q)\)-Szász-Mirakjan-Kantorovich-Stancu operators with three parameters \(\lambda,\alpha,\beta \). First, the moments and central moments are estimated. Then, local approximation properties of these operators are established via \(K\)-functionals and Steklov mean in means of modulus of continuity. Also, a Voronovskaja-type theorem is presented. Finally, the pointwise estimates, rate of convergence, and weighted approximation of these operators are studied.
