In this paper, we generalize a sequence of positive linear operators introduced by Ismail and May and we study some of their approximation properties for different classes of continuous functions. First, we estimate the error of approximation in term

We present three new approximation properties of the Balázs–Szabados operators. Firstly, we prove that, in certain cases, these operators approximate some super-exponential functions on compact intervals. Next, we provide a new estimate of the err

We construct a new volume preserving map from the unit ball B 3 to the regular 3D octahedron, both centered at the origin, and its inverse. This map will help us to construct refinable grids of the 3D ball, consisting in diameter bounded cells having

The present paper deals with a generalization of the Baskakov type operators, which preserve an exponential function and approximate functions with arbitrary order. We give some direct results including error estimation and quantitative asymptotic fo

In this paper we study some approximation properties of a sequence of positive linear operators defined by means of the squared Szasz-Mirakyan basis and prove that these operators behave better than the classical Szasz-Mirakyan operators.

In this paper we estimate the speed of convergence of the difference $L_n(fg)-(L_n f)\cdot (L_n g)$ towards 0, where $(L_n)$ are positive linear operators used in the approximation of continuous functions. We also study in what conditions the formula

In this paper we study the uniform approximation of functions by a generalization of the Picard and Gauss-Weierstrass operators of max-product type in exponential weighted spaces. We estimate the rate of approximation in terms of a suitable modulus o
