Abstract

In the present article, we study a generalization of Szász operators by Gould-Hopper polynomials. First, we obtain an estimate of error of the rate of convergence by these operators in terms of first order and second order moduli of continuity. Then, we derive a Voronovkaya-type theorem for these operators. Lastly, we derive Grüss-Voronovskaya type approximation theorem and Grüss-Voronovskaya type asymptotic result in quantitative form.

Keywords:

Gould Hopper polynomials,
modulus of continuity,
moments,
Voronovskaya asymptotic formula,
Grüss-Voronovskaya type asymptotic result.
