Approximation of functions of two variables by modified Szasz-Mirakyan operators

100%

Herzog M.

Commentationes Mathematicae

2012

tom 52

nr 1

In this paper we study approximative properties of modified Szasz-Mirakyan operators for functions of two variables from polynomial weight spaces. We present some direct theorems giving a degree of approximation for these operators.

Mahmudov N. , Kaffaoğlu H.

Open Mathematics

2010

tom 8

nr 2

399-409

In the present paper, we introduce the q-Szász-Durrmeyer operators and justify a local approximation result for continuous functions in terms of moduli of continuity. We also discuss a Voronovskaya type result for the q-Szász-Durrmeyer operators.

Walsh-Marcinkiewicz means and Hardy spaces

Nagy K. , Tephnadze G.

nr 8

1214-1228

The main aim of this paper is to investigate the Walsh-Marcinkiewicz means on the Hardy space H p, when 0 < p < 2/3. We define a weighted maximal operator of Walsh-Marcinkiewicz means and establish some of its properties. With its aid we provide a necessary and sufficient condition for convergence of the Walsh-Marcinkiewicz means in terms of modulus of continuity on the Hardy space H p, and prove a strong convergence theorem for the Walsh-Marcinkiewicz means.
