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

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 approximation properties of the operators V_{n,\alpha}^{\ast} are studied. A convergence theorem of this type approximation for locally bounded functions is established. This convergence theorem subsumes the approximation of functions of bounded variation as a special case.
