Approximation by Bézier variant of the Baskakov-Kantorovich operators in the case 0<α<1

2 years ago

Abstract The present paper deals with the approximation of Bezier variants of Baskakov-Kantorovich operators \(V_{n,\alpha}^{\ast}\) in the case \(0<\alpha<1\). Pointwise…

On an approximation process of integral type

2 years ago

Abstract In this paper we study a class of integral type positive linear operators depending on a parameter \(\beta,0\leq\beta<1\). Approximation…
