On a transformation of a sequence of real numbers Open
In this paper, we determine finite sections of a regular transformation, using random variables which follows the geometrical law, respectively Pascal ′ s law and the central limit theorem.

Approximation properties of λ-Kantorovich operators Open
In the present paper, we study a new type of Bernstein operators depending on the parameter . The Kantorovich modification of these sequences of linear positive operators will be considered. A quantitative Voronovskaja type theorem…

Convex sequences of higher order Open
In this paper we study the class of convex sequences of higher order defined using the difference operators and investigate their properties. The notion of the convex sequence of order r ? N will be extended for r a real number. Some neces…

Approximation Properties of Bivariate Extension of q-Stancu-Kantorovich Operators Open
In this paper we introduce a new q-Stancu-Kantorovich operators and we study some of their approximation properties. Furthermore, a Voronovskaja type theorem is also proven.

Note on a $q$-analogue of Stancu-Kantorovich operators Open
The goal of this paper is to introduce new q-Stancu-Kantorovich operators and to study some of their approximation properties.A convergence theorem using the well known Bohman-Korovkin criterion is proven and the rate of convergence involv…
