Abstract
In this paper we consider an extension, in the sense of Kantorovich, of a linear positive operator of Bernstein type L_{m,r}^{\alpha,\beta}, introduced by D.D. Stancu in the paper [7]. For this extension we establish some quantitative theorems representing estimaitons of the orders of approximation, by using the first and the second orders modulus of continuity. Also we give an asymptotic estimation, in the sense of Voronovskaja.
