Some properties of modified Szász-Mirakyan operators in polynomial spaces via the power summability method
Braha Naim L.
Journal of Applied Analysis

EN
In this paperwe will prove the Korovkin type theorem for modified Szász-Mirakyan operators via Astatistical convergence and the power summability method. Also we give the rate of the convergence related to the above summability methods, and in the last section, we give a kind of Voronovskaya type theorem for A-statistical convergence and Grüss-Voronovskaya type theorem.

In this paper we introduce some linear positive operators of the Baskakov-Durrmeyer type in the space of uniformly continuous and bounded functions of several variables. The theorem on the degree of the convergence is established. Moreover, we give the Voronovskaya type formula for these operators.

EN
In this paper, we present a sequence of linear positive bivariate operators and investigate the approximation properties of them. Next we study the rates of converge of this approximation by means modulus of continuity and functions from Lipschitz class. After we give a Voronovskaya type theorem for n Morever, we give an r th order generalization of these operators. Finally, we investigate approximation properties of this generalization and observe the rates of convergence for them.

Starting from a differential equation [formula] for the kernel of an operator [formula] with the normalization condition [formula] we provesome properties which are similar to properties proved by Ismailand May for the exponential operators. In particular, we show thatall these operators are approximation operators. Moreover, amethod of determining [formula] for a given function isintroduced.
